Remember you can buy Nlx on cryptopia. But the swap takes another 5weeks. So you can wait to swap at same time with cryptopia. Or you can swap already with dev Trystan. Who is been very active in the NulleX testnet channel on telegram. But remember only send to the new wallet after swapping to new NLX.
