It's a fairly simple process.
Make sure you write down your passphrase, and save the private keys somewhere safe.
Then, send a test amount of BTC to test the wallet.
Finally, use the "Transition Bot" in the ByteBall Wallet and follow the instructions of sending and signing a message to the ByteBall addressed provided.
That's it! You'll get an estimate of how much BTC you'll receive.
And here's an idea, reroll that liquidity into BitConnect and earn even more back later. (Steemit doesn't like BCC links, so please let me know if you'd like a referral code :])
Let me know in the comments if you got it working! Or, if you have any questions ask and I'll do my best to assist.
Cheers!
