ethereum and bitcoin are still the best. if you decide to buy another coin, then choose coins that have been listed in the top 100 list on the marketcap.
but it would be better if you update the title of your post. became "Best altcoins to invest for 2019"
I think so, but however, the profits of investing are not as good as past. Seeing market prices continue to decline. Not to mention the cost of mining of BTC is not comparable with the selling price so that it has an impact on the circulation of altcoin in the market. So by the way, can investment crypto or altcoin still be the ideal investment this year?
