in last three days ago, bitcoin price is down and if I can go back to that time, I will buy bitcoin as much as I can so I can sell it right now. the price is dropped too much and this makes people buy much of amount and they are expecting the price will be up in next days and it is happening right now. but we cannot go back to the past and we only could enjoy our day and make the best we can so our day will beautiful. I learn from my past to not regret something that I missed and I need to take a lesson from that moment so I can move on.
