Right at this moment, the stock markets are probably the worst places to "invest" your savings. This is my opinion, and I believe that we are now in a bear market for stocks, and probably for dollar based bonds.
You don't "invest" in crypto-currencies, but you speculate on the exchange rates. Having said that, I believe that Bitcoin is a good store of wealth, and ranks alongside gold and silver coins. The interesting newcomer is the legal tender coin announced by Tuvalu - it is the first one to be manufactured from rhodium,which is more valuable than gold.
