I think regular users don't have to download 100GB+ of blockchain in their Bitcoin Core wallet unless they plan to run full nodes, they simply can use pruned mode or SPV/Lightweight wallet such as Electrum and MultiBit.
when you downloaded the ''blockchain'' for the first time how long did it take you?
and what is the expected time to sync?
I tried only once to download the blockchain .
As I have free and unlimited internet connection in India( reliance jio unlimited free internet data 4G ) I tried to download the blockchain but when I started to download I found it is much complicated to complete the download because , I found that something the speed of the downloading the blockchain was slow ( may be due to Tue server of of blockchain but not sure ) .
But after about 20-30 GB it canceled the download . Because I was fully irritated for this long procedure of 3-5 hour .
Secondly I thing it is not much profitable to download ( if you have no aim to do something experiment ),.
Profitable? How can you think about profit when you only download bitcoin's blockchain?
