TRX is a solid coin because it was created by a strong team, and they have a pretty good platform that actually has some use cases. However, when you look at its price chart, you can see that it has already grown very significantly, so 10x growth is probably a big overstatement. It's also unrealistic because that would make TRX #3 by market capitalization after BTC and ETH, and while Tron is good, it's not that good.
As for ZIL, it's way less popular, and it's currently almost at its ATH, so buying now is very likely to be a mistake. Then there's SXP which is more of a shitcoin than a decent coin because it's not even in top-100. It can grow a little, of course, but I wouldn't invest in it because I don't see anything interesting about it.
So out of these options, I'd probably go with TRX but wouldn't keep my hopes high. I'd also consider investing in DOT because it's relatively new and yet the project is very strong and quite popular.
I guess anyone who reads something here and thinks that they should do it, should not do any investment neither. There is really not good enough reason in the entire world to make an investment based on anything you see online from someone else. Everyone should do their trading or investment based on what they think will happen and not based on what others said will happen, those are different things.
However I do agree about the other parts, TRX is definitely a strong project, not saying it will go up, but usually in crypto strong projects will end up higher eventually, even if it crashes a lot it will go up eventually, eth was like 88 dollars just like 15-18 months ago, now it is 2.2k+ or so, which is why TRX will be fine. SXP though I do not agree, it is bought by binance, so even if it is a shitcoin it is binance's shit coin and we know what they do those.
