And maybe OP is trying to talk about 10,000 USD but put in a dot instead of comma between 10 and the last three zeros which would make you a bit more curious as how to take care of this much capital and to get it apportioned among many coins and go for it. But a wise selection could really lead one to a good return from the investment and when the market is favorable too, it is worth putting in $10k.
I am sure he is talking about 10k and not 10, its a common notation to use the dot instead of using a comma.
People know that putting all your eggs in one basket is not good. Similarly the only crypto one needs to invest in is bitcoin. Rest are all trash. Next thing they should invest in is stocks and commodities because they play a reciprocal role with crypto. Hedging is an important thing to do even if people dont do it much.
