please suggest me some best altcoins that can easily give 2x profit if I hold them 1-year.
There are many I guess but only if the market will cooperate. If the market will be more bearish than bullish for the entire year, any good coin cannot even give you that. But assuming that the market will be in its good shape for a year and its performance will also be good, I think you can have the top altcoins. x2 is not that big after all. You can have ETH, XRP, BNB, EOS, XLM, LTC, and other top coins. Even Bitcoin can give you that x2 target.
Long term investment and can give 2x profit in one year I think altcoin have good position in coinmarket and have higher increase volume on exchange market, you can try for investing long term about one year with ETH, XRP, XLM, LTC and BNB coin, I think above coins have potential to be 2x profit with holding one year later.
Definitely long term investment can give 2x or more profit that may return. Well, if the user can wait on that long term investment for 1 year definitely can have a nice return but the question is would it be effective? Is the user can manage the emotions by doing such things to wait?. This are the questions, that are very challenging as the user become part of the crypto currency community.
In my opinion, if you want to make double profits, just investing in some top coins like BTC, ETH is enough to help you do this because in fact this year both coins have increased very high and still maintaining that stability during this time. I think that if you choose a good time to invest and have a specific investment strategy, you will easily win when participating.
Of course, prices are not always stable but these two coins are always selected by many investors and do not take too long to wait. In addition, you can also look for some good projects to make profits faster but the risk will be very high.
