I am a little hesitant to choose altcoins at this time, according to friends, which altcoins are good to buy and can give a profit to me?
Altcoins to buy you can see on CMC or similar sites, in my opinion it would be so much better than to listen somebody's else opinion because there is just a statistic, and nothing else subjective.
Listen to others is good because you have an idea about the coin but don't depends your altcoin to them. Buy a coin that you already research and you already believe that have a future.
