bitcore is indirect developed by bitcoin core team
because it just implement their bitcoin code improvements
without waiting years for a bitcoin mining pool dictatorship consensus

this is less time consuming than u expect for a skilled dev to take bitcoin core team work and implement it in bitcore
and this way make bitcore the ultimate productive test chain for what might come to bitcoin months/years later

limx_dev for sure keep developing any project he have commited himself too
so dont worry about BSD BitSend

the BitCore work will even have positive effects on BitSend because he can get in touch with newest Bitcoin mechanics
and evaluate them at BitCore and based on this choose if they get included in BitSend
