Depending on what kind of investment that you are doing but for me I'm doing a long-term investment trading which really benefits me because I'm kinda person who has patience in waiting and especially that we already have experienced on how high BTC and any other altcoins have come so far which makes me even wait for more until it increases again in the future. In short-term investment, it is more in buy low and sells high, same as the long-term but for now, it is hard to do a short-term due to the incredible decrease of prices which really doesn't benefit us all. That is why I'm focusing on the long-term for now.
