I know a blockchain wallet is a safe way to store, manage, and spend your cryptocurrency. I know all about the types of wallets ranging from Cold storage to hardware. Recently I decided to use a VPN when carrying out a transaction. I know I am not that techy but I have got to ask, is there / will there be a security issue when handling such transactions?
Malicious VPN provider may be involved into
Eclipse attack the aim being to isolate your transactions from the legitimate nodes and redirect them to nodes under its controll.
Thus, your primary concern when deciding to use VPN should be the selection of reputable and well known service.
