Burst is a great project, but sadly there are no incentives to mine it at the moment. Unless you have a BIG data center sitting unused seems that you would do way better simply buying it.
Yes.. for solo mining I agree, a lot of TB is needed.
However, you can still pool mine and you still use minimal power. In that respect you can make a profit long term.
What will the price be in 5 years?
If it was going to $5/Burst, would you mine now?
It will most certainly rise as all coins have in the coming years.
