1) Apparently, EVERYONE has difficulties with making "plastic cards" - due to Visa restrictions, contracts and laws. Even BCH promised it 6 months ago, but it's still not done. In short, I can't believe MNX will be the only exception.
not true. epayments works smoothly with plastic for almost 4 years. Minexcoin will be hidden behind ETF fund to work with Visa. The last won't be a problem.
