The risk is inevitable
hope I get more ideas from replies
Maybe I guess those average altcoin's price can be predicted using technical analysis of their price history especially using candle stick chart and line. You can draw lines to predict the next possible increase or decrease of it.
I don't think so, and you can try to draw the lines by yourself and see what will happen in a week later. The market right now moving in the various price, sometimes it's up, and the next minute, the price is down. Even if the price is up, we don't know until how long the price can stay at the high price. At this moment, it is better we know how much profit we want to take so we don't miss the good price to sell the coins, and if you're going to sell at a very high price, then you need to be patient to wait for the time.
