I think the best advice is to invest it in Bitcoin, not altcoins. Who knows how long till next altseason, I think Bitcoin will rise sooner.
When Bitcoin's capitalization is above 70%, then I think it is not the best option for investing in Bitcoin. Now I choose Altcoins!
The higher the capitalization of bitcoin, the more you should invest in bitcoin because the altcoin will bleed. It has been proven over the past few months when only the price of BTC increased and altcoin collapsed 5-10 times
