I don't see anything wrong with asking for suggestions about what business is good to start. Though it is imperative to have courage, still it is critical to know the factors that we should consider in building our own business.
For me, I'm gather all profit that I got from crypto trading and will start business as soon as possible.
The fact is that's not easy as it says because the competition is really high nowadays but that's right if you want to make the move, it's a better rather than do nothing !
