If you don't really need it right now, I would say it's a good investment. Right now BTC price is rising, we never know when the next dump will happen, but in the long term I still think BTC will continue to grow. You can of course try to invest in altcoins as well.
Investing in bitcoin seems to be an alternative to investing in gold. Bitcoin increasingly in demand by many people around the world because internet as a liaison. I haven't invested fully, still gradually.
