Again a very nice acronym!
Never used blocktrades before to be honest but saw many people using it and it looks like it is the common tool here to convert your well earned SBD or Steem in other cryptos rather than sending it to exchanges.
My phylosophie is to convert all my earned Steem or SBD into Steem Power. That way I can give back to the community and since I really believe in the future of steemit this will also be an investment.
Keep on the good work! And once more happy to have you here!
