price now about 100$ any may be need 1 Year to increase to 1000$
This simple won't happen, it will go down almost instantly because of lack of support. I'm not convinced any if you have serious plans for keeping this coin in wallet for a years..
Any idea when we can start mining this (hopefully get profits too after)
Probably when they releases wallet. Do not expect too much from this one. Everything is up to whales, but i doubt that will have same support like BCH had. Maybe we can see usual pump and dump, but in a volume like BCH had.
Did they solve the spending problem for Bitcoin Gold yet? I don't remember the name for the problem.
I don't know where you live, but you should go out from this cave! There is no problem, and never was.
This is from Bittrex Statement on Bitcoin Gold
Bitcoin Gold does not currently have:
Fully formed consensus code
Implemented replay protection
Adequate code for testing and auditing
Publicly known code developers
Bitcoin Gold codebase also contains a private premine of 8,000 blocks (100,000 BTG). Please be aware that if a market does open there is a possibility of the developers selling their premined BTG on the open market.
Did they fixed this?
