Is the fork still taking place at block 501451?
Yes
Okay one more question, how are the Satoshi's pre-mined 2,000,000 coins going to be sent to all BTC holders' wallets post the fork and when should I expect them to be sent to my B2X address?
"Satoshi Nakamotos Bitcoin" will be mined and distributed proportionally to all Bitcoin holders on the crypto-exchanges and wallets of our partners. It is worth noting that this present to users who supported us will be credited sometime after the basic conversion 1:1. Yes, you will be able to transfer them to your b2x wallet (it will be announced soon)
