Update is about the last one BTF : It seems that the exchange is opened and the source available, BUT note on the source says you should wait for release 0.15, master branch is not supposed to work. Bitpie supports BTF but you can't redeem your private keys with it. Bither doesn't support BTF yet. update of the update: I tried the fullnode wallet : it needs libsodium too and it doesn't download the blockchain (yet)
