If you have some tips in additional then give some.
One should always know when to leave. When the bitcoin price was at $ 17000, I bought it for $ 17000 and I remember hearing a lot of people saying it would drop to $ 5000. At the time I went research more and sold in the $ 16000. it was a good decision.
because I'm sure the market will go up...
the market may never recover. look at many altcoins, many of them do not return to have the same high price of the past
So, they buy high and sell low.
How will you know exactly that the price is high?
