Wow, I'm shocked that Ripple received half of the votes. I get it that this coin does nothing then once a year or two goes up 10x, but even so, it's a Top 10 coin and therefore it's growth can never match that or a coin in the Top 100 (or lower even) that can gain 50-100x. Nevertheless, everyone is entitled to their own opinion 
Yeah, everyone has their own point of view to asses the coin. I also don't agree 100% for the result of voting. I think Ethereum is still better, but the thread owner didn't put Ethereum on the list. I don't know in what way, OP choose the random coins. By the way, what coin do you think better, sir?
Well I voted for HOT, as I'm a hodler of this "non-blockchain" project, and also because it's up 150% in 2019 so far. In comparison to other projects on that list, it has outperformed all others in Q1 so far (as far as I can tell). This doesn't mean it will increase the most for the rest of the year, but it stands a strong chance.
In all honesty, I think it's impossible to tell in Q1 which coins will gain the most value by the end of Q4. Crypto moves much faster than normal markets and 9 months away is the equivilant of 9 years in traditional markets. Probably it will be a coin that performed the best in Q3 or Q4 that will get the title of best performer in 2019.
PS - you can call me dragon, rather than sir
