... doubling every two years (so 16MB in 2018)
What does it mean ? It will keep on growing like 8, 16, 32, 64, 128, 256, 512, 1024...
That means we are going to have 1GB block limit by 2030 on XTcoin ?
Awesome
That rationale does not make sense. We are assuming that storage space will be doubling every two years but possibly this won't be true for long.
Also whats Bitcoin XT? Is it an altcoin?
It is a fork of Bitcoin Core with some features but it hard-forked which makes it kinda-altcoin. However, if majority users use it and if it becomes the larger chain, it maybe considered as main chain.
