So, what's better? Buy with ETH of with BTC?
Only want to buy a very small amount (like $50).
The reason I ask is that transaction time with BTC are so long, and probably ICO will only last short time.
Never bought something with ether .. what amount of gas should I use?
With BTC, you can purchase full tokens. This will be a bit slower though.
For ETH you need to calculate BTC - ETH first, how it is traded on that day.
