How can I find out the status / when I will receive it??!? I was told that the "slowdown" is due to
higher transfer fees.
Go to your favorite block explorer (try blockchair) and enter in the transaction ID.
Will these fees ever lower
I don't think so, at least on the 'main' network. For lower fees, layer-2s will be the solution. Unfortunately they're not
that ready yet.
and are BTC worth the investment still??!? (Layman Terms Please).
The transaction fees isn't really the identifying factor for bitcoin being a good investment or not.
