You have a good strategy I think. Knowing which ICOs are on the horizon may be a smart way to gauge when to accumulate and when to dump ETH. I'll keep an eye on ETH prices during and after those 3 ICOs next week and see how accurate is your prediction!
One thing that I definitely agree with is that it is smarter to HODL ETH than to buy into any one particular ICO. I feel like some of them could be amazing and groundbreaking, but that the majority of them will disappoint in the long run. The one thing they all have in common though is that they will be fueled by Ethereum, so why not just invest in the fuel? Looking forward to your future posts!
Yeah just buy fuel. Or buy shovels and sell them to gold miners.
It will be interesting to check my prediction next week.
I'll post for sure how accurate I was!
