Except with third party like Bank we need another alternative ways how keep safety and privacy about transaction fund withdrawing from Bitcoin or altcoin, many time withdraw amount above $200,000 in Bitcoin to bank next few days later have investigate from the bank about our money credit. Just one way how keep privacy with Bitcoin if have been legal currency transaction and we don't need third party for withdrawing Bitcoin or Altcoin fund to the bank. Need more than several years later if want to see Bitcoin or cryptocurrency have been legal transaction payment currency.
