Speaking of bitcoin, bitcoin has helped my life, especially in my family's current economy, which I can tell very well from before, and I regret a bit because I know a few new bitcoins a few years, if only I knew bitcoin from scratch maybe now I already a millionaire

Wow, you knew a "few new Bitcoins a few years", that might be a lot of Bitcoins. Bitcoin gave me profit that I can use for some things but in reality, I can't really use it or get it since I am thinking that the price might still go higher and I just need to wait but I did not. Investing Bitcoin is great but you also need to be patient and to be so informative on what you are doing and what is happening.
