Recently I have started to invest in altcoins and may give you some clue. I don't see myself as an aggressive investor. In contrast, I am very cautious about every penney that I invest. To learn how to profit from altcoins, I have to go through the failed process and I know it well. That's why I have lost money since I bought altcoins like ETH. Well, to be precise, the prices dropped and the money has not been lost in real because I still hold the coins and hopefully wait for the next bull run. Are I reasonable ? Hard to say now but one lesson that I have learned from this is that I am experiencing the market for real and trying to figure out a way to profit. Am I going to continue to lose money ? Probably yes. Am I regretting the investment ? Hell no. As long as the investment is affordale to lose, I am fine with all market situations. Altcoins are a great test for learning the real market. That's my personal reason for being interested in them.
