I don't know a coin can x hundres times but you want good investment. Just pick any coin that has real usage like LINK, WLD, SUI. Of course the top coins ETH, SOLANA, BNB are good choices too.
I think bitcoin and crypto have really changed the game. They are century-defining inventions, just like the internet and AI. Traditional brokers and governments will have to adapt to these changes, sooner or later.
I recommend the Exchange wallet. A cold wallet is good, and I am also aware that the FTX and MT Gox collapsed, but I have a friend's cold wallet that was hacked due to his mistake. I think Exchange's wallet is safer for careless people like me.
Soon, I think this broker would have many promotions for buying/using their own token. I am investing in Binance Coin (BNB) and it brings many benefits.
His team gets some insiders that know the plan and even Long before the news and then Short at Peak. His trade got 50x leverage and total value = 100M, that's such a bastard in Trump team.
