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 your coins is still in good shape now and also standing strong so I believe that there is nothing to doubt about them all, and also i believe that if you find questions in one of those ? all you have to do is release the currency and invest in Ethereum , or maybe consider investing in Binance together with those sets of coins?
because aside from being popular and legit, Binance is backed by one of the strongest Exchange that we have now in crypto space .
These altcoins that you mentioned are definitely will last long because these are in the top coins in coinmarketcap so I'm very sure that these coins can survive in 5 years. If you are planning to hold for long then it would profitable especially if the bull run happens they will pump for sure.
If for example the next Bullrun will not happen again, will holding all those altcoins also be profitable? I don't think so, although all these altcoins can last up to 10 years in the market or in the crypto space, because they can all get pumped when the market and Bitcoin have started to improve at market cap levels and prices are greater than now.
this is depending on your trust and belief and also specially if you know the word "Invest what you can afford to lose" and also knows the word HODLING.
