What I do not like about bitcoin is peculiar to all crypto currencies. Transactions are irreversible. You will lose your coins for ever if you make a mistake.
I think this is a benefit for finacial world, irreversible transaction mean we need to more aware about our assets, and also this can avoiding someone to mess with the chain
I feel this will also be experienced if I enter the cryptocurrency address incorrectly when I do the transaction, not only bitcoin, but also other altcoins like that, ethereum, ripple, eos, doge, litecoin, dashcoin, and others.
this must give us caution and alertness in making transactions, do not rush or try to memorize the address. because actually alamt cryptocurrency is designed long and random so that it is difficult to memorize by humans.
