Lock-in value
After purchasing the MD, users can choose to lock the MD for a certain period of time before trading. During the lock period, MD cannot freely circulate, but MDLife services and products can be redeemed with MD at any time. Even if the price of MD decreases, the services and products can be redeemed per the price at the locked time. After the lock period is over, the user can re-trade.
For example, a user purchases a certain amount of MD at the price of $1 and lock them. During the lock period, when the price of the MD drops below $1, the equivalent service can still be redeemed with MD for the price of $1. After the lock period is over, the user can either choose to re-trade the token on crypto exchange or choose to redeem the equivalent service at the market price.

Service guarantee
The MD offering price is $0.3 per MD. To ensure that user's rights are not damaged, MDLife has set up a service-based bottom mechanism to ensure MD’s value and price. When the MD price drops below the initial offering price, the user can still redeem MDLife services and products at the same price as the initial offering price.
For example, if a user purchases a certain amount of MD at the price of $0.3. When the MD price drops below $0.3, the user can still redeem the equivalent service with MD for the price of $0.3, which is not affected by the drop of market price.

Service pool
The use rights of MD are not limited to one service provider, they can redeem among different service providers. With the addition of service providers, the ecoservices pool will cover testing, cell storage, pharmaceutical trade, health products, cosmetics, big health services, medical beauty, online consultation and so on.
