crypto currency investing, anyone?

Like I said all investments are risky.I don't understand alot of investments. People try to get me to look into Gold/silver Ira but you never get to hold it like they say.You have to pay to store it and they take a pick.....sounds fishy on the taxes also
I've never paid a dime on taking money out of my IRA it's been a tax free investment from the start. True, all the investments are risky but gold and silver have been around alot longer than bitcoin and they will be here when bitcoin is long gone. As I said earlier, I've never heard any investment firm advertise bitcoin as a investment.
