I appreciate your opinion, but I would not say stupid to someone who has invested bitcoin. It's better to say that it all happens because luck is not owned by people who buy at the time of bitcoin at a high price. Maybe you also experience it. So you can say that. So better all that we make for experience in investing. And began to rise again by trading. By trading we may be able to profit little by little. may be able to return the money that has been lost due to the decline in bitcoin prices. Better to think positive with failure. Because of unstable market prices, I think trading is something better than investing.
