If you believe in the potential of Bitcoin and appreciate the advice of experts, you should not be too worried when the price of Bitcoin down but the fun again right. At reduced prices you can use cash to buy more at cheaper rates. when each Bitcoin increase too much or too deep, it is not too worried.
This has already been said more than dozens of times in here, if you really trust on it. JUST BUY, otherwise do not do it because you can buy in an all time high, and you can risk all your money
I am not buying anymore, in fact, the last time that i bought some bitcoin was on December the 10th, when it was at $11,000 if i am not wrong.
At some point we need to decide when it is enough, however bitcoin is presenting to us an opportunity that is probably not going to appear ever gain and that is to buy at these cheap prices, many people after the bitcoin cash fork could have bought bitcoin for less than 2k and decided to wait and that opportunity does not seem like it is going to reappear so if you are happy with the amount of bitcoin you have then you do not have to do anything but if you are still looking to buy this is the perfect opportunity.
