Low cap altcoin which is able to provide x100... very risky of losing funds maybe yes. But also nothing is impossible in crypto, anything can happen. If you are really crazy about the x100 price increase, just buy all the low cap coins and wait for the bullish moment, if you are lucky you will get it or you will also be hit by a scam coin.
I think you are right that it is too risky if he wants something that is too high for what he wants to get. Finding one that can provide profits of up to x100 is certainly not easy because the criteria you are looking for are, of course, quite a lot, and deciding which one to choose is very difficult.
Even though possibilities are always open in crypto and nothing is impossible, he also has to be realistic about them.
But if he wants to buy all the existing coins, of course, you need quite a lot of funds.
to determine whether they will be effective in the future and, most importantly, whether they will be profitable.
Everyone wants to succeed, but finding a unicorn coin with high returns is nonsense. Crypto has opened doors, but it has also opened Pandora's box of scams, misinformation, and market manipulation. People, be serious.
You say it would cost a lot to buy all coins. Is that a sensible plan? Spread yourself so thin you wont know what struck you. Who says all coins are equal? They're not. Some are scams designed to deceive you.
Being wise is more than "being realistic". Dont fall for every glossy new token on the market; DYOR. Sounds too wonderful to be true? It probably is.
