I do not think it is a good idea to buy now because the bitcoin price keeps rising.
If you already have bitcoin you can sell now and wait until it decrease again then buy back.
Isn't that contradiction?
If you think bitcoin price will continue to raise it can only mean that it is good time to buy and not sell.
OP i don't know what do you expect from answers, make your own choice:
1)If you think bitcoin will raise - buy it
2)If you think bitcoin will drop - sell it.
Yeah, if we believe that bitcoin price keeps on rising so it is very good time to buy it. Simply because when it keeps rising then we will get nice profit, on the other side if we know that it will drop then we should sell it as soon as possible to minimize loses then wait till reach the lowest price to buy it again then wait for the next pump.
