I've been reading up on the relationship between private keys and public keys (as well as hashing), watched a few videos, but I am still a bit confused.

I don't have a programming background and trying to understand it in a way so that I am able to explain it to an "everyday person".

What I found is that before a message is "encrypted" with a "public key" that key FIRST must be shared with the receiver.

How is that the public key being shared?

Thanks for your help, Arthur

Curious what you Guys think,

A number of currencies seem to have accelerated their developments recently, and it became apparent that they are much more usable than Bitcoin.

Of course, Bitcoin still stands as the most "hack-proof" network, with the largest community, however arguably, that's about it.

I've seen some BTC miners waking up recently, since due to price increase, it became profitable again to actually mine Bitcoin.

I am wondering, once genuinely another crypto wins over the market acceptance when it comes to payments, what are the realistic chances of Bitcoin staying above $15,000, maintaining Bitcoin's mining profitability?

I am about to order 10 x S9 antiminers for Bitcoin, and looking at things from the pragmatic point of view, I am debating as to whether it's better to get GPU mining mashines for AltCoins or S9s ..

appreciate the comments,
