Maybe my idea  will not be original ( even I am sure that will not be) but I want to say the mine and I want that my voice can be hear together with the others that might have my thoughts). There no secure place to put bitcoin or other altcoins (for the value they can have) except in our wallets. Every place out of those is not sure because the world is full with scammers who are ready right over the corner to steal those. So take those in our wallets, control from time to time and save fiat money to buy other for the times to come. The times when bitcoin will have real value and can be used in the right way into the real economy.
