UPD: Resolved!

Not know in details but problem with my local (ISP) DNS server. When I start bitcoind with local DNS - it fails to shutdown all time.
When I change DNS to 8.8.8.8 - and start bitcoind - shutdown works ideally!

Maybe my ISP blocks something etc. I just don't have time now to explore this question. Maybe later. For now I just changed to use 8.8.8.8 in my local net and problem gone!

Did you sent this to an exchange? If so, in which exchange did you do this? They are the ONLY ones that may help you.

Contact their support. Some exchanges just help you, others charge a fee to recover your coins and others don’t do anything. Just hope they help you, because no one else can.

If you own the wallet, recovering it could be possible (I’m not sure tho, as we are talking about the ETH and BTC blockchain). Disclose some details (tx ids, wallets/services used, etc).

Among all the cryptocurrencies in the space, I only make use of bitcoin for extra purposes. Such as, the purchase of personal needs like clothes, shoes. This is because there are stores in my locality that accept it. Meanwhile, others are meant for profit-making, particularly during trading.

people are already very tired over these difficult two years. they hold coins that have lost 99 percent of their value and of course, people keep complaining. this will happen until we will see the altcoin season
