My wifes, moms, nail ladies- grandma died and I bought there house.

I just BET you would attract the attention of a big thinking friend who would share knowledge with you.

That POS Realtor was long gone and made their $10k in commission.....but we were stuck with picking up all the pieces - finishing their job - and having to coach an owner into reality.  2) The average Realtor has no idea how rental property pricing works, what attracts tenants, how to screen tenants, and how to sell investment properties. 

@Kevin Ely You should be most concerned with #2.The reason B&H real estate is attractive is because you can safely leverage. 

The attractive thing about cryptocurrency is that it's like magical internet gold because we know how many of these coins are circulating and how many will be produced by a given certain year thus being able to know what the market cap of certain coins are.Either way, as @Jon S. mentions, this will be here to stay as currency, commodity, and utility.

Knowing the local rents and quality of tenants the property will attract.
