I am not a big investor, neither do I have lots of assets, but if there be a room for me to have a big amount of assets, or turned to be a big investor, I will put them on crypto currencies. Maybe bitcoin has gone so high in price, there are other good coins to buy and hold for the long run. Though, it is said that for the long run bitcoin is number one and other altcoins in the first 20 or 50 position.
Investment is all about risk, the fear of squandering your capital, you take a risk to put it into something that will yield profits, gold is good for little to no losses, but with little returns, and on bitcoin, the price is so volatile in its ups and downs. But one thing is for sure in bitcoin/crypto currencies, they bounce back with profits if one can be patient enough.
