Thanks for the chart. The best thing to do is to hold on to your bitcoin with the belief that the price will definitely rise one day. Selling your bitcoin cheap or at a loss is like throwing it away and you have not lost anything until you decide to sell it at a loss. Bitcoin has died several times and yet waxing strong.
I believe in Bitcoin and in the fact that in the coming years it will not have equal crypto currencies. Of course you can just hold. But in my opinion it is boring and in the end you will still be left only with the number of bitcoins with which you were at the beginning. Personally, I prefer to trade. It doesn't matter that I bought 1 Bitcoin, for example, for $ 5000. If I constantly sell it and buy (successfully) even at prices below the incoming price, then in the end result I have the opportunity to increase the initial number of bitcoins. Therefore, in the future, I will get much more profit than if I were just holding.
