Money
If you are investing money into bitcoin and other coins, always plan ahead, if your earning are 400$ daily, try to buy 100$ worth of precious metals for the long run and reinvest the rest into bitcoin, like that if something happen to the system you have a back up plan, i dont want to sound crazy but if the place where you live gets hit with mother nature like puertorico and caribean islands, emp attack, solar flares, martial law, war, etc always be prepare for every situation, jp morgan had bought all the silver and goverments been accumulating precious metals, i believe the dollar is going to collapse one day in our timeline and hopefully bitcoin would replace it but if it doesnt its always good to have something to hold like gold or silver
