As Amsterdam says crypto currencies are in freefall at present, especially Bitcoin. Best stay away even if you're a market investor.
The blockchain technology is not going away and crypto currencies are here to stay, that's not say a lot of these coins and tokens won't disappear if they offer no value...which differentiates the gambling from the investment.
Some of the tokens I'm investing in are for healthcare, and the ability to transfer medical treatment plans seamlessly between institutions, or be shared with other medical professionals anywhere.
If you've ever had a missed prostate cancer screening because you "dropped off the system" as my dad had and then been diagnosed, or been prescribed the wrong drugs because your previous records are unavailable, or have to get X-rayed and start from scratch every time you change dentists because they have no prior history...the benefits of having an absolute and total medical record that you can transfer in seconds are incalculable.
It's a long job to sort the wheat from the chaff though, so there's a lot of learning and researching involved. Definitely not for gambling, but there's a more beneficial feeling from aiming to invest in something that will improve lives.
