I think it's easy to understand how to invest on this one... the first one is like a bias... you need to understand that from now on... this amount of ether will be locked! until the next year!
So, you may ask.. what will ether be valued in 100, 200 or 300 days? more? less? same?
My view is that it will eventually value more... at least that's what I say it has more probability to happen.
I think at a first stage you do really need to mark down your pawn... invest the minimum... 0.01 ether or less (if possible)... But always invest on the first bit. Why? because there are far too many variables to risk, and if you are wise and you wish to control it, you would like to know about when would be the right time to invest.
Think... ETH will increase value because each time someone invests on an ICO, the amount of ETH free to trade is less... therefore if the demand is likely to be the same or increase... prices will go bum! Therefore fewer people can invest in ETH... therefore capitalists of ETH will decide the final price in my view!
that is the plan
