Heck if all the exchanges transferred their BTS to lock them up for BEOS, imagine how the price of BTS would sky rocket. This raindrop idea is great because if you want the token you have to lock up your BTS, and to do so over time. I am no expert, but I assume exchanges wouldn't want to hold and lock up mass quantities of BTS, especially when I have to assume this bear market is literally almost over (considering past trends).
