My friend is All In in Altcoins - Wants to increase his BTC position afterwards

Hey!

A friend of mine is actually a bitcoin understander and wants more bitcoin, but he fully thinks in a fiat mindset in the moment.

He says: why should I go all in in bitcoin now, when there's coming the biggest altcoin season we have ever seen? I will go all in in 2-3 very good altcoins, no meme coins, and then I will outperform bitcoin, and try to sell for fiat when it's overbought and the RSI shows a potential top. After he successfully have sold he would hold the fiat cash amount for around 1 year to watch the crash and then he wants to put every dollar he has into bitcoin.

What are your opinions on that? Even if you are a hardcore true and loyal bitcoiner...are there any points to support his plans? Or is it too risky at all?

I don't want to play father and teach him to be humble and only stack sats... but I think if he would do that with 10% it would be better than with everything he has

Thanks!
