To protect our self from scammers we don't let others to know that I have a Bitcoin. What we are going to do if I have a Bitcoin we just hold it and we keep it in a very safety places. When the time will come when the Bitcoin reaches in a high value its time to sell our Bitcoin and we can have earn more profit.
That beats the spirit of blockchain and its goal to become rather a main stream currency. The post is aimed at increasing the utility of cryptos, while avoiding being scammed, rather than sitting on a pile of cash that slowly turns into dirt.
