Plus, you can trade with that amount or just wait for alt pump.
Yeah, but you also need to take a big risk by buying that coins. Because we also don't know is the price of that altcoin will increase or not, it's kind of gambling though.
If you want to hold for long term then better option is to invest in bitcoin rather then going for altcoin as we don't know how long that particular coin will survive.
you can more quickly rich with altcoin compared with bitcoin, but if you just want to hold, yes altcoin not the right choice, because altcoin nice to take short-term profits. but some coins could be a long-term investment options, such as ETH.
