if you have done research with these altcoin and you think these altcoin are indeed good for investment, then you don't need to hesitate to invest in these altcoin, but I suggest you to set aside 30% of your money and invest in Bitcoin and Ethereum, because until whenever the price of Bitcoin and Ethereum will definitely continue to increase, so you will definitely get a big profit in the future, if you hold Bitcoin and Ethereum in the long term.
I think you have given a very good suggestion that if one completes his research and information then he should not hesitate to invest. If anyone is still having trouble choosing coins, then my advice is to invest in the top 100 coins available in the market, because you can trust the top 100 and they have the potential to make a profit.
If one has good capital then he should invest half of his capital in bitcoin and Ethereum.I think 30% in Bitcoin and 20% in Ethereum should be invested, because investment in Bitcoin and Ethereum is the safest and most reliable. While altcoins have excellent profit rates. This way you divide your capital into different tokens.
