Actually, it should "only" be a solution that leaves YEMCHAIN and vice versa, to be able to enter YEMCHAIN with the values of other blockchains (e.g. Bitcoin, Ethereum etc.). Research and development took place under the project name "Bridgecoin", but once again the fact was confirmed how unsafe it would be to cooperate with a conventionally listed coin - especially in terms of value stability. So why not create a new coin right away that can do the balancing act !?
