] Overall no one can confirm the true prediction of the Bitcoin price both now and in the future, time, the market, which determines the changes of all of these.

What I want to say is: you fell asleep when Bitcoin was at the $ 6000 level one year ago, that's when you should think about investing in as much Bitcoin as possible.
However, if you look at the day-to-day movement of Bitcoin, it is also a good thing if you are investing, but not in the long term, perhaps, the weekly is suitable for now the development and movement of Bitcoin.

What is certain is that all the decisions are yours to invest, if you are sure you do, if you are in doubt back off.
