Would you say its more than even say 50 max? There are over 2k cryptos. Most are worth nothing. But how many are actually worth something?
Its hard to say but i think altcoin with market cap value more than $10million is worth to invest for long term. Some people said its better to invest in top 100 coinmarketcap but i think coin with market cap more than $10million good altcoin and having a good community
