First of all: if you dont like to shutdown your antivirus firewall -recomended- you must to allow the coin-qt.exe program installer as a true positive program without virus, because all of the antivirus programs detects as a false positive.

​

Also allow coin-qt.exe to communicate with the blockchain network and so sync.

 

That means download all the blocks of the cryptocoin blockchain

​

A) Some coin's developers offer a binaries windows installer as Dash DASH (dashcore-0.12.2.3-win64-setup.exe) or

Bitcoin BTC (bitcoin-0.20.1-win64-setup.exe)

​

B) Others, like Bitcoin BTC too offer bitcoin-qt.exe in a zip bitcoin-0.20.1-win64.zip or

like Experience XP offer XP-qt.exe in a zip file

BuzzCoin BUZZ buzzcoin-qt-v3.2.exe

Espers ESP Espers-qt.exe

and so on

​

In case A)

run the installer

-remember look the antivirus don't eliminate the installer but if it so, recover it from the quarantine place-

​

It is recommended install in the default location the program choose

- for ex.

C:\ Program Files \ coin

​

As we said, others coin's developers provides -usually in a zip file- the coin-qt.exe that you must run each time you like manage your wallet

​

In case B)  (preferred by me)

download the zip file, unzip and run the coin-qt.exe

​

​

But, one of the important thing is that almost for all the coins, the path where the blockchain is default saved is in:

​

C:\ Users \ youruser \ AppData \ Roaming \ coin

remember that

​

Downloading the entire blockchain of the cryptocoin of your interest depends on:

​

• the size of the blockchain

for ex. today 20201127 , 

(aprox. 335 GB for Bitcoin BTC,

22,543 GB for DASH,

28,555 GB for ZEC Zcash,

34,968 GB for Litecoin LTC, etc.)

• your available bandwidth,

​​

• the available bandwith offered by coin's developers,

​

• power of your computational resources

​​

• and other things ...

​

You have to spend a few hours and a couple of days or

in a bitcoin case several weeks to sync your wallet....
