1GB = 1BTC

prices here are low. everyone trying to get in cheap desperately. e.g offers of 0.01btc per gb or less. to get 130GB you needed to link 100btc no small amount. holders are being offered 1btc for all that or 1/100th of the worth.
a 100btc holder gets approx 0.2% of the initial market. if the coin is successful they are asking to buy from you 1% of all the available coins for 5btc which is a big chunk. since waves and lisk are distributing and waiting a few months id wait for market prices i believe it will be higher.
remember 1GB is a lot!!! there is only going to be 1000TB or 1PB in total.
each 1GB you own now in a few months will give you another 0.1GB too so you are not only cheaply selling your byteball at this price BUT also your second round share too
current second round is 100MB per 1GB byteball and 62.5MB per 1btc
