please suggest me some best altcoins that can easily give 2x profit if I hold them 1-year.
Within a year, this is actually enough time to get 2x profit. my advice if you have a lot of capital you should not forget about Bitcoin, because this is the main. In my opinion, the Top 10 on CMC will (To The Moon) according to the news circulating that Bitcoin will halve next year. ICO projects, IEO can also get 2x profit even more, if your research is accurate. for now I am holding TRX (tron) and waiting for a miracle to come.
