H160 - Is the first 61eb8a50c86b0 the one you mentioned as 53 bits?
If that's what you mean, I have it.

It's not. It's 52 bits. Do you know anything about the hexidecimal base? It's really simple: one char is exactly 4 bits.
For those who hunt vanity address prefixes:
Address A: 19vkiEajfh6SFxXEJoFEJxQm7VJucnHqn7
Address B: 19vkiEajfiE6Wwh83YH2LMV1rgx5pivsnY
If you believe address A is better because it has a longer prefix:
Please stop what you are doing and rethink about your life, maybe also learn about how numerical base conversions work.
If you still didn't get what's wrong here:
Address B is 32 times more difficult to find, and it's also 32 times closer to the correct prefix of the correct H160. Oh, and except for statistical analysis matching prefixes does not help with anything. Again - if it would, then Bitcoin itself along with several other cryptos would be broken and their value would go to 0 before you even manage to sell the reward for fiat money. Do not listen to the voodoo magicians, you will waste your time. If you still want to lose it anyway, at least understand why you can't base your search on vanity address prefixes, you will most likely find things that are way off from what you think you're searching for.
could you explain to me how you can say that address B is closer to hash160 searched?
