I feel like COMIT started to get somewhere and just stopped.
Need fully functional UI wallet/POS. that allows the swaps and exchange of BTC, LTC, Doge, Monero, ETH, PAY, and TenX.
If you can pull off BTC to ERC20 these should be easy. Add lightning. Make this wallet/POS integrate with the most popular Wordpress and goddady payment modules, integrate square, and quickbooks, and accounting features that can put all the info into a CSV.
Have both a light client (app) that runs off TenX nodes, an a full multi node client. Build and sell the multi node in a fancy TenX box and make user tutorial on how to built them.
If you do this I will go door to door to every business for you, setting them up with the hardware, software, TenX card, and educate every merchant.
And you will have accomplished the END GAME!
