Going Fully Crypto...Please advise

Blockchain technology has gone beyond Financial sector disruption
I am confident of a widespread adoption of Cryptocurrency and Blockchain in it's entirety in a very short while.

Adapted from Telegram Crypto group
I am quite old to Cryptocurrency but I wasn't opportune to network with Crypto folks earlier.

I would love to ask some questions about Cryptocurrency and it's acquisition particularly in Mining Cryptos

Anyone with an idea or a good site or app for mining altcoin?

I hope to help people live above poverty and empower youths too aggressively using Blockchain technology. I am getting questions from friends but My answers aren't really good enough for them to comprehend fully about the potentials that lies in the Crypto sphere.
Most likely, I will be taking courses on Cryptocurrency pretty soon to acquaint myself about the world of innovative Blockchain.

Any recommendations about good Crypto mining sites and Blockchain courses?
