Well mrai is an altcoin that wont charge anything, soo you send those as payment to family, but for this be possible to happen we do need some  exchanges support to let mrai grow, something at the moment inst possible. Mrai is changing already some people life, that are able to survive with the daily captcha service and selling their mrai daily, if we had and exchange already we would have around 1-5 btc of transactions already, and much more will come once listed.
