I have always lost more money trading and made money by investing and holding on to investments for years. I suggest newbies to invest in good crypto coins, I think the top 20 to 30 coins in coinmarketcap.com are pretty good to diversify and to stay invested in. And for God's sake, ignore any recommendations given in troll boxes. Always do your own research as it is your own hard earned money.
It's not enough just to based to that top 20 coins in coinmarketcap.com. They have a volatile price since then. Only bitcoin is meant is fit for long term holding as future is bright as based on the development of bitcoin since the beginning.
Those other alts are not meant for long term holding. When I say long term holding, it's years in the making and bitcoin is the only fitted to that role. Those other alts that have been on top like you are saying in coinmarketcap.com is profitable by doing regular trades and not just by holding since they are heavily manipulated due to numbers of distributions.
