Totally agree that all-out investment is not a smart decision. For investment purpose, voalidity and risk should be always put into consideration. In cryptocurrency world, there're mainly business forms like this: opeing exchange, mining machine, wallet in payment field and other deriviate product. I personally suggest invest in payment field with either less volatile and lower cost to run. Bitcoin ATM would be the best choice to most of ordinary investors to get involed in cryptocurrency business. Here is one for your reference.

viva@outlook.comEveryone will advise you to invest a part of your investment in cryptocurrency and see the results. If you are satisfied and think that it is good than any other investment, then you can add more money in your investment. If you did not satisfy with this investment, you can put the rest of your money in some other business. But it is not good to invest all your money together.
