That means, he can buy 50% more satoshis with the same $1,000, but since I don't have any BTC reserves, how can guarantee the "stableness" of the coin?
Are there any solutions to this such as offshoring this a decentralized exchange?
Thanks!
That would not possible OP. It cannot be done to have a stable coin paired by bitcoin enables you to buy more btc when btc market price drops with the same money you bought to that stable coin. It is very confusing and you only just thought of a price drop from btc. What if btc starts to increase it market price? What happen to your stable coins or your btc bought? Imagine a disaster? That would probably your stable coin you like to create.
Cryptocurrency were being back already with dollars or reserves like golds. The moment one like to acquire a certain coin definitely buying it would be more easy and that money use to buy will be put to reserve as it will be return to you when you sell the coin back.
So how could you earn in cryptocurrency?
It will depend on your patients or the market. If the coin you brought make a price increase then you can sell your coin and make a profit. Just remember that the market price of a coin depend on the demand and supply. The higher the demand for that coin then the higher market price it could have. This is why most of the coin has been used as an exchage for services and to buy products to which it could create higher demand from the consumers of that said products and services. That coin will have a significant market price increase with the demand from the consumers and vice versa if there is no demand for that coin its market price also significantly drop which could make you some losses depending on your patience or attitude towards the market of the coin you buy.
This is why bitcoin would be the most appropriate coin to start with when one would like to earn. Others could hold it for a month and then sell and others also could hold it for a month and sell just depending on the market. It could also mean losses or gain depending on the attitude of the holder.
