What do you expect will be the role of bitcoin and altcoin in the upcoming global economic crisis?
first we need to survive in this pandemic, then we will see what the impact will be on the economy. so far it is very difficult to make predictions of what will be in the future
If so what is the best altcoin to buy and hold for the next five years?
this Is another very complicated issue, altcoins depend a lot on bitcoin, when the bitcoin price increases a lot and stabilizes altcoins start to increase a lot also in relation to bitcoin. But leaving my opinion I think ETH is the best option
