IMO there are some issues with the model presented
So people buy at $10 per coin and are not able to sell until it reaches $100. Coins are only bought and price increases (pump) and once they get to $100 many will want to sell and price will go down (dump)...
"prevent sell" must mean the coin would be traded only on your platform (not cool)
There are only 5 coins over $100 (according to CMC at least) . None are stable coins. Ever wondered why ?
How will you ensure the coin will have a stable value ? Mint ? Are they backed by stacks of real $100 bills ? Will you buy tokens off the market ? Coins don't just "stay stable" you know...
If you have a better idea to avoid the crash, please share and we would be happy to consider it.
Your coin, your problem

To me it just sounds like OneCoin 2.0 stable version ...
Hahaha, lovely, how you said OneCoin 2.0... you made my day... Well, in that case, you may need to read the coin distribution again. Selling token is not the main purpose and this is why out of 100,000 distribution there will be only 15,000 token sales during the whole period of time. There are limited tokens available to sale per day and per user. Users can earn tokens only with sharing and bringing more people to the community. The purpose is mainly to develop the community. 1 Dollar coin does not need a strong community but 100 Dollar does need a community.
The token is made with proof of work and proof of stack, the users have to earn it.
The buying option will be available as well but between users. Users can sell and buy tokens to each other.
I think, there might be a miss understanding, or we did not clarify it. The token purchase price will not be 10.00 forever. The token price is bound to community members, more numbers of community members more the price will increase until the final destination. Let's suppose one buys a token at 10.00 today, after a week, it will be 22.55 (just an example), while reaching to the final destination the last coins will have a price of 90.00+.
The main purpose of the token is to build a community first so even if we are not able to sell a single coin, it does not matter to us. We have sufficient funds to take the whole project to the destination.
