Users who have BTC will get as many Bitcoin 2s as the amount of Bitcoins that they have. 1 for each 1.
That already happened last 2018 and congrats to everyone who claimed BTC2 that day. But today you can never claim any btc2 anymore. if you want to have it, buy on crex24 or birake btc2 is a good coin and it's stand on the market turmoil last 2 years ago and got stability on it's price.
