Lot of investment in 2019 is almost dump and must pick some coins that listed in coinmarketcap also those top coins in good exchanges. Making investment from other coins can't taking it so long to pump.
Yes. A lot of new coins have started to appear in the market so we should make more research about their background so we will not be easily tempted with those shitcoins. I still consider bitcoin and ethereum as my best coins for investment because they have proven their potentials a lot of times.
Basically, everyone will definitely prefer BTC and ETH anytime and any day, these are still the most promising coins, this 2019 is even worst for prediction on new coins because most of the new coins that has been coming up end up being dumped by investors who no longer trust in a long term investment with them.
And aside BTC and ETH, other coins I can still trust to yield good investment this year will be the ones at the top 20 list on coinmarketcap, other coins are just to be gambled with, which I know that some of them can give a very good profit, if we are able to study them well, this is worth some experts are good at, trading shitcoins.
