How any buyer gonna buy site with these issues
He need to pay unpaid members first to reach a good price,
No one gonna buy site with debts and broken traffic even for free
Stop members investment in the site
pay invested amounts without profits
maximize ads in the site to accomodate for bitcoin price change
you can delay payments, put maximum payment amount during certain period but with strict deadline to regain members trust
Solutions are there if you like to solve.
