Of course youll get a lot of answers here but cant you see theyre just promoting coins that they already have. I strongly suggest that you may want to do your personal research regarding to that. Theres is not assurance in every coin that they suggest Im sure you knew that coz every coin has an unstable price. So if you want to invest on a particular coin I think you should research about the project and read some articles and their whitepaper. Then you can decide if you would continue or not. Good luck mate!
