Not rich but do have $500k investment on crypto. haha Only a few people do have this kind of numbers on their portfolio.If you do just simply Buy all on Bitcoin you would surely profit or even just 2 coins btc & eth.
It might not give guarantees but i would stick to these established coins rather than risking into new coins because even if you do see it do have potential,you cant be sure if those would boom up later or just simply die just like on most shitcoins in the market.
