If you do not know how to trade, then the long-term investment is what you need. The main thing is not to be nervous, invest money and forget about it for a while.
if long-term investment, patience is the most important, we must be patient and not easily affected by market conditions or bad news. we must be sure and keep holding our coins even if it goes down. I believe that long-term investment is the right choice for now because I believe that the market will return to its highest point.
