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.
This... the stock markets and equities markets will easily see a 1-1.5 year correction once the bull trap sets in.. and the housing market, jobs/economy will follow... we're in an "everything" bubble where all things you can own are overvalued, and everything will see the chopping block... Crypto is only safer since most of its bleeding and correction are near its bottom so the maximum level of potential exists in speculating... you even lose holding fiat because its losing at a rate of 3% per year due to inflation.
