^My recommendation is to do the research yourself and always keep your ear to the ground for new innovative coins.
This is the same fallacy as the "sports bet pickers". Everyone picks a winner eventually. Proving one has a statistical edge when trading alts is a hard endeavor though.
Look for new innovation, wait for it to come out and start trading (fuck icos lol) and buy some when it evens out and just sits there in accumulation phase. This way the market has already decided a semi-fair starting price before you even buy in, which gives you a bit of insurance that you aren't buying vaporware like what is possible with icos. Buy only as much as you are willing to lose, even if its only $100 that can turn into $1000 pretty damn quick with a decent alt pick. This is the only way I can have a defined risk/reward and know what my potential entry/exits are before i buy, this way I'm not freaking out when it moves against me a little and I'm also not tempted to take profits early.
If i had to pick a few coins to rise at the moment, I'd pick Sia/Naut/Amp/byteball (long term)/ & possibly LTC next week after segwit activation (I have the least amount of confidence in ltc, yet I still think its a pretty decent shot to go up a bit more, though probably nothing astronomical). I hold a few of each of the mentioned coins. Sia/Naut have been rebuilding since it's lows on high volume and steady gains. I am 100% positive Sia will be 100+ sats soon, and naut I'm hoping for a 3x from it's current point. (I hate the idea of investing in Naut, but its supply is super low and I've seen worse coins take off). Amp has been rebuilding beautifully and could also 3x from its current point, in my opinion.
Also always decide whether you are buying this coin for the longer term or just for a quick 1 day-6 month trade. It will highly impact your trade, one you want to make sure to sell early, the other you want to make sure to hold on for dear life. You never want to get the two mixed up, you will either hold too long and miss out of profits/bag hold, or you will sell too early and take a small win when it could've been a life changing win.
Don't buy anything because I said so though, go check out every single coin on poloniex and find the "golden eggs" that give you the best chances of success. Look for steady rebuilding & consistently higher than average volume. Don't invest any more than you are willing to lose (this way you are never tempted to puss out and sell early, very important).
I'd rather everyone learn something from each trade they make (whether profitable or not), I feel one can't learn from simply buying something on recommendation. The thought process of why the purchase was made in the first place isn't there to learn from.
Sorry to blab, just like to try to help.
There's just so much more to the trade than the "pick". I am a firm believer that the exit strategy is more important than the entry.
I wish you the best of luck with profits. Get in there! :p
