By banning Bitcoin purchases via credit cards banks and credit card companies are actively stopping cryptocurrency investors from buying the dip.
I see this as the first wave in a much bigger scheme to halt the ability of the working man to get their teeth into this type of investment.
First they will ban purchasing with one card, then they will ban the use of debit card purchases, then you will need a special "account" to purchase - and the cycle goes on and on.
The banking industry is using this opportunity to monetize avenues into cryptocurrency investment and just like forex and public shareholdings; cryptocurrency will become a club that the average Joe has to jump through hoops to join.
