Welcome to the BitcoinTalk forum.
If you intend to invest in bitcoin in any legitimate way, then you are in the right place. Judging by your posts and merit points, it appears to me that you are doing well to be here. Good luck
I encourage and salute you for your courage to sell your bike to start investing with a small amount. This will be like a demo account to understand the basics of investing in a practical way and for a small amount. But the amount is too small to diversify your portfolio. I really hope that you will earn twice the amount you invested so that you can at least buy a new bike, so there is no problem in diversifying your savings.
I advise you first to look at the various topics that provide explanations on how to use a private wallet (not on Binance) and how to save your savings yourself. Secondly, never venture into investing what you fear of losing, no matter how safe that investment may seem to you.
