I bought some bitcoin in March 2017, sell half of it in Dec 2017 and hodl the other half since then. The current downward trend seem to last for a very long time and I'm quite upset about it. What do you guys think? Should I hodl or sell all my BTC now?
You should hold your bitcoin do not sell it now because the market is on down trend and if you sell it out it will result to a low income. In addition to that, if you continue to hold there is a chance that you could earn big income simply because the price of it will rise again. The best thing to do right time is to hold it and be patience and do not be scared even the price goes down because is normal and you should know that the price of it is volatile.
