You want to invest in long term but you expect to get your return very "Soon", i think you better to do trading instead of investing. Don't think you can get x10 or even more just in one over night. If im being you with that amount i will all in into BNB and staking my coins in Binance.
Staking for long term, that would be still a decision wise idea if you've got nothing to do with those and you just want to receive passive income and as well as some perks while it's there.
But that won't give assurance as you won't hold the keys. It's the counterpart of staking into an exchange even though it's the most popular one.
