It sounds like you had a significant involvement in crypto back in 2017, and stepping away must have been a difficult decision given the circumstances. Revisiting your holdings and work now could indeed be worth exploring, especially since the cryptocurrency landscape has evolved dramatically since then.

From the screenshots you’ve shared, it seems you still have access to your wallet and possibly some funds or mining rewards. If that’s the case, the first thing you should do is:

Secure Your Wallet: Make sure your wallet is accessible and protected. If it's been untouched since 2017, verify you have the private keys, seed phrase, or any other credentials. If you're using an old version of wallet software, consider updating it, but only from the official sources.

Assess Viability: The viability of your holdings depends on the cryptocurrency you mined and whether it's still active and supported. For example:

If it’s Bitcoin (BTC), you could check your balance using a blockchain explorer with your wallet address. Bitcoin’s value has seen tremendous growth since 2017.
If it’s an altcoin, confirm whether the project is still active and the coin is being traded on exchanges. Some coins from 2017 have lost relevance or even disappeared.
Policy and Regulation: Given that internal policies in your country pushed you out of crypto, it’s crucial to understand how the regulatory environment has shifted since then. Are you now allowed to access, trade, or hold cryptocurrencies? Compliance will save you headaches in the long run.

Community Insights: If you’re unsure about the technicalities or the status of the coin/project, forums like this one or dedicated subreddits for your specific cryptocurrency can be invaluable resources. Provide as much detail as possible without exposing sensitive information.

Potential Gains: If your wallet still holds Bitcoin or a valuable altcoin, even a modest amount mined in 2017 could be worth a significant sum today. For example, Bitcoin in 2017 traded between $800 and $19,000.

Take this step by step, and if the funds are still there, this could indeed be a shot worth taking. It might even rekindle your interest in the crypto space. Best of luck, and if you need any guidance, feel free to ask here! The community is always willing to help.
