We all know the advantages of BTC, but what are some of the disadvantages??
Well one that i can think of is that it is still not perfectly anonymous. Personally i'd like to see bitcoin evolve into the future into something like XMR with essentially in built coin mixing. This is probably not necessary but rather an add on.
Another thing is that, fees are often high.
Also, blocks are 10 minutes on average in between so that means you're probably not going to be able to get stuff irl instantaneously without the merchant having to trust you.
for me this is another disadvantage of bitcoin No Valuation Guarantee Since there is no central authority governing Bitcoins, no one can guarantee its minimum valuation. If a large group of merchants decide to dump Bitcoins and leave the system, its valuation will decrease greatly which will immensely hurt users who have a large amount of wealth invested in Bitcoins. The decentralized nature of bitcoin is both a curse and blessing.
