October 23, 2017: BTC is divided into 2 block chains, giving rise to Bitcoin GOLD (BTG), together with the 2 existing BTC and BCH
November 24, 2017:
BTC is divided into 2 blocks of blocks, giving rise to Bitcoin Diamond (BCD) which, together with the 2 existing ones, add up to 3.
BTC tries to divide into what would be Segwit2x, but although Fork is not produced, if future values of the currency are quoted (so it is assumed that sooner or later the Bitcoin currency SegWit2X B2X can be used)
BTC is also divided into another chain of blocks, BitCore (BTX), a project started in April 2017, which runs its Fork in the month of November
Thank you for that, but the question is, does anyone know if the BTC should be imported into the Nano as Legacy or Segwit?
it is advisable that you use segwit, because you send your transactions a little cheaper.
Personally, I would recommend that you use Segwit, there are no problems with that.
