Bitcoin is not a platform, it's a digital currency/asset that has few advantages and it's more like the peoples money because it depends on it's decentralized capability, if you are talking about High Yield Investment Plans or MMM Ponzi schemes well Bitcoin is not like them.

And do not expect a big income or gains like HYIP from Bitcoin, you need money to invest buy dollar cost average weekly or monthly or when you can afford it and you also need a lot of patience, I will advise you do some research first on Bitcoin, even if you buy how are you going to keep your Bitcoin safe? Learn about Bitcoin wallet and keeping recovery phrases safe first.

Create time for yourself and do a lot of digging on Bitcoin before you start buying, find and know the best wallet to store your Bitcoin and also know that Bitcoin investment takes time to yield, this is not something you can make a lot of money from in weeks or few months, so invest what you can afford to lose as it's still a risky bet.
