Be careful where you invest your money, many altcoins are down 95% and most of them will never recover again, it's why I still prefer investing in new projects that haven't pumped in any bull market before, for this reason alone whales can pump the coin or tokens and also in every bear market new utility use to get into the space, making the old utility less attractive.
Please specify what altcoins you mean. If there are many altcoins down more than 90%, it is normal because we are in the bearish season. As long as they are trusted altcoins, I think there will be a chance for them to rise up again. Unless you choose new altcoins with weak fundamentals or no fundamentals, it may disappear and never rise up again.
Anyway, it is quite strange that you prefer to choose new altcoins. New altcoins are riskier, they may never be pumped or never increase their values. There are many new altcoins that only have big prices when IEO or ICO only. When IEO, ICO, or public sales end, the prices just drop constantly. Why don't you choose top altcoins, dude?
