sell now or buy more and wait for the rocket?
Buy more RIGHT NOW! And wait for the rocket. Cointelegraph issued a video that bitcoin is flying towards moon! So what are we going to do now? Buy more bitcoin, because probably this would be the last time you can see bitcoin at this price. So, wait for the market to boom, and sell. Probably its ath is at 30k.
Follow this advice and get much profit in future. Bitcoin will be popularized and therefore its value will be constantly increasing. I am sure soon it will cost much more.
