First, I recommend not to do the short -term investement. As market move all over the time, It will hurt your health. I hope u do the long - term investment and starts from big exchange like binance or upbit
Great advice, I also trade long because this market is very volatile and if you don't have much time here for sure the money you work for will be lose. Trade with caution, don't just buy penny coins look for a stronger coin.
