This is my advice you can shifted another coins because there are many top altcoins so It's your own research which will be best revenge. At this time if you can buy top coin then no need to wait very long time because we're nearly bull market. There are many coin price will rising in bull market so just for now you can buy dip price top altcoins for next bull.
I once bought a coin that, judging from the CMC rank, was very far from the top 100. and it was my fault that in the end I suffered a huge loss because the coin was unable to develop and become a dragon.Therefore, starting from this experience, for now I only choose to invest in coins that are in the top 10 of CMC and hope that the price will rise in the next bullrun. didn't expect the worms to turn into dragons again.
It's not enough I guess to see only if they're in the top 10 of Coinmarketcap because there are some altcoins that were once in the top 10 but ended up in a bad performance after a few years, in my opinion its better if we buy altcoins before altcoin season and sell when altcoin season ended because holding altcoins for long term won't give us certainty in the future compare to Bitcoin.
