I have all of these coins:
ETH 40%
CARDANO 20%
POKALDOT 20%
TERRA LUNA 5%
THETA 15%
Avax: 10%
Are my coins going to last is it likely?
All the coins you mentioned can last for 5 years or even more than 5 years because their trading activity in the market is always active. But it would be better if all the coins you mentioned could be sold when your planned profit has been achieved. You can at least sell half of the whole thing.
Wrong, nothing is certain , even that nowadays those coins has good trading activities yet in the following year there might be something can happen so expect no permanent in crypto mate.
but if you think that there will be a future for these set? then Buy it now and maintain in your wallet but I will not take all of those, i only have Ethereum and Cardano as those are what i believe will gain more sooner .
