I doubt that, the popularity of BTC really increased in 2020 and still increasing in this year as pandemic has not yet subsided. What I mean is that, the milestone might be a good reference, but if you are seeing that way, you might also consider other factors such as popularity of it.

I'm still really seeing this through until it reaches maybe 50k then sell. And might then see if it goes up or down without any regret in my side

I bought BTCs from bitcoin.com.au around 20 hours ago and it is still showing 0 confirmations in my wallet. I checked on the blockchain.info (I am only a newbie) and to me it looked as if the bitcoin address from which they sent had  unconfirmed deposits into that account. Could it be the reason for my transaction not being confirmed?

What happens if the transactions doesn't go through for a few days and get lost? does the coin go back to the seller/sender OR he can double spend by associating the higher network Fee?

I sent my last transaction with a low fee and the "replace by fee" option enabled, just to give it a try. Now when I right click the unconfirmed tx in the History tab and select "Increase fee", it gives me the option to set a higher fee. But when I try to sign the new transaction, I get an error message that looks like this: http://imgur.com/a/O1vyD

Should this feature work when using Electrum with a hardware wallet? I did not click the "Final" checkbox after setting the higher fee; is that required? I'd welcome any help!

EDIT:  Might the error have anything to do with the original transaction only having one output?

it is really difficult to understand how to calculate activity ?  and time X 14

Can any one explain clearly .. How do i calculate ?
