For sure, IMO.
Investments are calculated risks, which are outright distinct and different from gambling.
People evaluate risks in different manners, according to their own interpretations or current financial status. There are 4 stages in life, survival, security, success and significance. If you are in the first stage, which your whole survival is entangled with the number in your life savings, then I would advise you stay away from investments, any kind of them, just focus on creating more values for yourself until you are able to generate some sufficient amount of money.
However, when you are in the second stage and further up, you could now then evaluate your options. Depending on your preferences, you could go for housing properties if you like passive cash flows, stock market if you like liquidity or cryptocurrency if you prefer speculations. They are very similar, which they all can earn you money, but very different in terms of the risks associated.
There are people who believe in the cryptocurrency, or the digital gold, Bitcoin, and they are willing to fork out every cents of their savings to pump into the investment. Bear in mind, the cryptocurrencies or the blockchains technology generally are still vastly in the development period, which still have a long way to go until mass public adoption. It's wise to think twice before you pump in any money into any investments, especially cryptocurrency - Bitcoin.
Anyway, if you are still wondering or confused, simply don't. Because you are not prepared, both mentally or physically.
