I agree with much of the post but question a couple of areas. First, when it comes to cryptocurrency, I agree with taking out your initial investment after an increase. After doing so, everything else is free money. Also, diversification is generally a good idea. However, so many of these coins are virtually brand new. I don't know how anyone could project increases into the future. My gut tells me that only a handful of these coins will have much of a future. Fomo is rampant right now and knowing the best time to get out is nearly impossible. What will our investment be worth if the feds decide to make cryptos illegal? Look up the tulip mania in Holland for a historical reference.
Side note: I'm not all that tech savvy; any good hardwallet recomendations?
