It looks like selling your crypto for money when they are profitable is more safer than holding them for long, my point is only very few coins are worth holding for many years, if you still doubt about this go on coinmarketcap and look at most coins that came into this world in 2018 many of them have no volume again, the shocking one to me is gowithmi, a project that my elder brother praised so much at the time but today it's volume is not up to 50k, many projects will face same fate, be smart
sometimes we need to be smart when it comes choosing a crypto project to hold especially for long term, because to be honest not all can guarantee a good return after all and not all coin in the market can last long like bitcoin and ethereum and that's the sad fact.
Because imagine i have different coins in my lost wallet way back 2017 and they all have good volume and value, and now i noticed most of them are shitcoins..
