some people including me tested out crypterra. first there was many problems for getting the hashrate who was orderd. now, since a few days they send the payments in a big bash to many wallets with only 100sats/b so the transaction get never picked up by the miners cause the fee´s are way too low. the incoming transactions of theyr wallets was made by 500sats/b so we now know that they exactly know what they do and have to do that every transaction got stuck and nobody get his "mined" coins. so be carefull to investing in crypterra!
