Is it optional if somebody could not give the private keys? It's confidential right?
Its not optional mate. You can't claim Forked coins without private keys.
What services are available any links..?
No mate. I'm just a small scale Crypto Investor. Not much knowledge on web development.
Note: As I said earlier in this post, this service is only for the people who does not want to get in touch with tech stuff and have small balances. I would not loss my several years old BTT account for some satoshi.
