I think Ethereum is the most grounded and have the option to get by for long time in light of the fact that Ethereum network is so huge and many individuals are include and they trust to utilize the Ethereum blockchain. My idea is, don't simply hold however when your impulses and exploration let you know that you want to sell a few, do what needs to be done without a second thought.
Try paying attention to ADA mate Cardano is one of the most potentially and promising currency for long term and if EThereum network not work about the High gas fees then this will be overtaken by at least Binance or Cardano in the next years.
so expect something bad about ETH if they fail in delivering the best result of ETH 2.0
all of OP's altcoin investments are good and promising crypto assets. survive in the next 5 years? every that altcoins will last indefinitely in the future. which has no definite future imo is a meme token/coins.
Meme coin actually also has a future like Dogecoin although others are still being questioned because there are cases where cheap tokens that have no interest will be eliminated from exchanges such as Vidy tokens on local exchange Indodax.
How long before dogecoin makes a high profit? 2-4 years? this ahs even being questioned if will survive because of no good movement for long .
just this year that this meme coins give this high increase but just after a week drops back down and now showing no good movement to recover .
this same scenario like what Shiba Inu now .
agreed on this one , Meme coins seems to be not the best for long term instead for short or semi long term only .
