I think companies or those who have done business or invested in bitcoin get results. Because when the bitcoin price is low you can buy and when the price is high you sell it so there is no term loss in bitcoin business.
but sometimes we are greedy, and this is what makes us lose. when it's lucky and the price is on the hill then we expect the price will rise again, and market going down and we bear the loss
once we become greedy in anything, then get ready to get lost too much. there are no instant ways to reach success, not in bitcoin and other works. we need to work hard to reach success and we need time to see what we've done can give a good result in the end. without hard work and work smart, we cannot reach what we want. and if we want to be a bitcoin business success, we need to know a way that will help us to reach success. success does not just have much money but we have a time for our beloved family.
