every altcoin has its own development and type, that's what makes altcoin has its own market, like now a defi-based project might be more noticed and interesting because it's the current trend.
Current trend? For how long? By mentioning by "current", it is implicitly denoting it is kind of not persisting one, right?
I'm not ready to believe into anything such "current trend" because I just want a longer duration based things which can be low in ROI but must have definite future. In recent time, I have seen coinmarketcap is adding new filter for "defi" still I am not ready to believe anything fancy but lagging in innovations.
Altcoins may hit moon but not each and every altcoin; there are possibility for less than 1% of altcoins in the markets to get chances to perform well in coming months and most others will get delisted from exchanges. I'm not discouraging people here but I'm just talking about the fact what I have observed in last 4 years. Altcoins are 10x more riskier than bitcoin investments so do not invest all your money into altcoins.
