Hey there! So the HEAL tokens can be used in the following ways:
(1) Doctors and clinics can pay for leads and services
(2) Pharma companies can pay for communication research
(3) We can reward patients who write useful content (eg. reviews)

The list of countries is not final, because the strength of each country's Etheal community will be an important aspect.

Other important factors:
-population of the country (eg. China, India, Russia, Japan)
-volume of medical tourism in the country (eg.: Thailand, South-Korea, Singapore, Israel)
-language of the country (eg: there are several Spanish speaking countries in South-America)

So the list is not final, but as soon as we have certain information about expansion, we will communicate here.

We would suggest to contribute on our subpage. Most important thing is that only Ethereum is accepted during the crowd sale. Use an ERC20 compatible wallet when transfering your ETH.
Please note the actual gas prices for ETH, this may prevent inconveniences with pending transactions.

Currently the price is 1 ETH = 1250 HEAL, so currently, it's about 0,34 USD/HEAL.
