For sure best way is to diversify. In crypto investing for me the best is 50/50. I split them on risky and very risky. The first one keeps me in the game, the second one make me win in the game. Last year I made 50x with my risky investment and 2018 i'm continue this way. Now I'm very interested in one ICO that I think will win the game for me https://bitcointalk.org/index.php?topic=2724094.0
I'm searching for other ICO with big ROI, so if anyone finds something interesting write to me Thanks.

The Android app is very helpful I'm using the Android app to watch my tokens in HitBTC its works perfect I am looking forward for new releases to see how the product is growing and other exchanges are added.

I am sure that my investment will return multiplied by the end of the year!

I'll invest! I think ROI is definitely worth it. I think TBT will going to hit $1 by the end of the year!
