POKALDOT 20%
TERRA LUNA 5%
THETA 15%
Avax: 10%
Are my coins going to last is it likely?
Anything can happen from now till five years coming so we can't determine the obvious answer to your question. But i think majority of the coins you have mentioned can surpass the five years you have mentioned to many more years coming. Ethereum is a good coin with good project developers. Ethereum has the potential of surviving even after 5 years so we can expect more from Ethereum. Cardano and Poka are also good coins which I expect more movement from them.
