If not airdrop like "airdrops" you still need to hold bitcoin or zclasic coin to have bitcoin private. But the ratio is not fair i guess since the bitcoin price is higher that zclassic why bitcoin holder still get 1:1 ratio ? i hold 1 bitcoin worth of 7k usd and i get 1 btcprivate and i hold 1 zcl worth of 100 and get 1:1 ratio too. So i just need to hold Zcl right ?
Yes, you are correct. If you did not have any Bitcoin but you have Zclassic, you will receive 1:1 ratio (for either Bitcoin and/or Zclassic), but make sure to go look on Zclassic site and maybe use on of there wallets just to be sure. They developed wallet just for this purpose to ensure coins there will be matched with equal amount of Bitcoin Private.
It is an uneven ratio if you are comparing value of those two coins, at least what the value has been, but it is an unusual fork because it is not a split off of the main blockchain it is actually a merge of two different existing chains, BTC and Zclassic into a single new & hopefully improved blockchain.
And know one knows how the market will react... one of them may not keep the value in favor of another.
