Hello, i discovered recently a coin named simba storage token (SST). Their goal is to store Bitcoin very securely and it seems to me thats its safer than a cold wallet or an exchange. For me, its a good project and i dont see any kind of this project in the market. Its not very well known yet and i hope we can start a discussion about the potential. Thanks! (Sorry for my english, i am not a native speaker.)
