| Scalability / number of transactions |
Theoretically unlimited number of transactions as payments are decentralized (peer-to-peer). |
Theoretically unlimited number of transactions as payments are decentralized (bank-to-bank). |
Technical limits are unknown. Reportedly, VISA processes ~24,000 TPStransactions per second and Mastercard ~5,000 TPStransactions per second on average. |
Technical limits are unknown. Reportedly, PayPal processes 192 TPStransactions per second on average. |
TBC |
No, the blockchain can process only 7 TPStransactions per second and is chronically congested.
The "Layer 2" Lightning Network allows "millions to billions" of TPStransactions per second. |
Theoretically unlimited TPStransactions per second due to variable blocksize (since May 2024). |
No, the blockchain can process only 56 TPStransactions per second, although this is currently sufficient. MWEB (MimbleWimble Extension Blocks) improve scalability by aggregating multiple transactions.

Transaction fees
(assuming no currency conversion) |
None. |
Depends on the bank or country. Usually no fees, with some exceptions (e.g. for large transfers or certain international payments). |
Depends on the card issuer and country. Various fees, both variable and fixed, are charged and add up to on average around 2-3% of the transaction value. The fees paid by the merchant/recipient. |
Various fees are charged, usually paid by the merchant/recipient. A typical fee for a domestic online purchase would be 2.9% + $0.30. Payments to "friends and family" are free. |
TBC |
Depends on the desired transfer speed and the network congestion. Transactions are "competing" to be included in the next block - the higher the fee paid the quicker the transactions will be confirmed (and if the chosen fee is too low, the transaction may fail altogether). Due to the chronic network congestion and small blocksize, transactions tend to cost more than for other cryptocurrencies. During the crypto boom of 2017, average fees reached $60 per transaction. Fees are independent of the transaction value, hence network fees seem low for large transactions and high for small transactions. From 03/2017 to 03/2024 the average fee was about $3.50source but of course this is highly dependent on the BTC/USD exchange rate.
Cheap transactions using the Lightning Network are also possible. But will still incur fees for opening/closing the channel and the Lightning node |
Very low fees. Normally, a transaction costs a few USD cents. |
Very low fees at current network usage. Normally, a transaction costs a few USD cents.

| Fungibility Fungibility means that it is not possible to identify a specific unit of money and therefore it is not possible for units of money to become "tainted" or accounts/wallets to be blacklisted by the authorities. |
Generally yes, but it is possible to identify specific banknotes by their serial number. |
No |
No |
No |
No. Each unit of money is uniquely identifiable and all transactions are centrally recorded. |
No. Due to the public blockchain, coins can become "tainted" and wallets can be blacklisted.
Source of funds can be obscured by mixing (CoinJoin), with various downsides.such as minimum funds needed, the time and fees for mixing, and the likely blacklisting of mixed coins from CEX and off-ramping providers |

No. Due to the public blockchain, coins can become "tainted" and wallets can be blacklisted. Coins used in MWEB transactions are fungible.By obfuscating the sending and receiving addresses as well as the transaction amounts, the individual units of Litecoin used in MWEB are indistinguishable from one another and therefore can't be identified and potentially blacklisted. |

Everyone can see the funds of a wallet on the blockchain. |
Everyone can see the funds of a wallet on the blockchain, except those relating to MWEB transactions. Transactions that are done on MWEB remains private indefinitely and the corresponding wallet balances are therefore hidden. However, when moving funds from MWEB to the normal blockchain an aggregated transaction is created, thereby making the total funds publicly visible again. |
Only the owner knows his/her total wealth. |

| "Store of Value" narrative |
No, fiat money has an unlimited supply as the central bank can create new money, thereby devaluing existing money. |
No. It is inflationary like all fiat money and additionally can be programmed to expire after a certain time.The government could theoretically give out money that expires within a certain period of time or money that could only be used on certain items, which could be used to induce behaviour that the government is seeking. For example, in the Chinese CBDC pilot program, money has an expiration date of a few weeks because authorities are hoping to drive consumption. |
Yes, deflationary. Fixed maximum supply which is further reduced by lost wallet seeds. |
Yes, deflationary. Fixed maximum supply which is further reduced by lost wallet seeds. |
Yes, deflationary. Fixed maximum supply which is further reduced by lost wallet seeds. |
Probably yes. There is a perpetual coin issuance (tail emissions) with inflation asymptotically approaching zero. Supply is further reduced by lost wallet seeds. |
