I never been experience such things, and so I didn't ever wanted to. I don't have much BTC in my wallet, just little for me to help additional support for my daily needs. I am using wallet which is very popular in our country and that is coins.ph. It has several divisions for the different crypto currencies like BTC, ETH, and others. It is very convenient for me because I can easily convert my crypto currencies into our currency whenever I wanted or needed it.
