I am very sad if it is now a lot of their bitcoin dropper is something that is feared by all the bitcoin users that now let alone they will take the bitcoin that has become the property of others and I think to overcome it I have to anticipate by installing how things will be can not be cracked by anyone.
Hope you are doing well with your security. I think most hackers will never crack your BTC wallet if you do not share the information for them. I left BTC in the wallet on the Bittrex exchange, and it was a safe place to hold the BTC
When it comes in security in investment Bitcoin is best for it, that's the reason choose to invest in Bitcoin because they know once they invest to it they can bring huge profit to them and their investment is really secured. For me only Bitcoin has safe investment, so i recommend dont waste your time for a finding a good coin to invest because you might get a scam investment, so it better if you invest to those coin that lots of people are believed and trusted.
