I'm not a fanboyy of some cryptos but why are you not proposing some cryptos like XRP or LTC which are in the market for more time than these in your sentence?
Maybe he think those token would be rise higher than XRP and LTC since each of them are sitting on #3 and #5 as the biggest currency. He want to invest in smaller crypto to get bigger profit
Yes, that is true, but I think investing in the top coins will also be very good if indeed it is an investment for the long term and again it is an advantage that at least will certainly be obtained. If we invest as discussed in a token at a current low price, then it does not necessarily have high prices in the future and of course investing for it will have a greater risk of loss.
