How? ETH got a ton of companies already and is monopolizing the smart contracts niche. Do you really think Stratis can compete? Also there are more competitors coming like Ubiq... maybe Ubiq is a better pic?
Did you even look at the image? The only reason for which ETH has got a ton of companies is because: 1) Network effect in the smart contracts area. 2) Semi-centralized coin. Stratis having a similar platform with C# instead of the crappy language used in ETH already makes it superior.There's a ton of %1000+ performers. All of the decent ones actually. Then there's a ton more around %100-%999.
If you believe in your own words, why not invest everything you have into several ICOs? 
If you want massive gains, comparable to Stratis, the ICO needs to have a fairly low CAP/raised amount. Otherwise it will not work. It needs to be $10m or less.
But the fun fact is, even after the shitshow that BAT was, with tons of money raised and most of it by whales, if you bought in the market, you would already be up %100+:https://coinmarketcap.com/assets/basic-attention-token/#markets
I regret that I sell my Strat before, I dont know that this will gonna happen. The price of Strat is increasing now, though I dont have already Strat. Still Im observing this coin.
You can't really tell what the best price for selling is. Either risk and hold, or play it safe and take some profits. If you do the latter, then don't complain.
