My opinion is buy and hold 50% of your capital outright bitcoin then buy any top altcoins with other money. bitcoin will give you big profit share anytime and better profit than altcoins if bullish market comes next. In my opinion it is absolutely stupid to buy new altcoins to take risks that will increase the amount of losses. In fact if you want to invest in crypto you have to stick to buying and selling in the crypto market.
He said very small amount only, while your recommendation of 50% seems a lot already, but to invest in a top altcoin is much better than a new coin. A new coin can't be a top coin yet because in order for a coin to climb the ranks, they must have a really good volume first. Even though he also mentioned old coins, not all old coins are top coins or are performing better, so it's better to be clear here.BTC is always a good investment but it does not mean it can give us a profit any time since it's also highly volatile and bull runs don't come often or stay any longer once it arrives. Some top alts are still smaller than in BTC so their pump potential might still be high, no wonder why some consider them too.
