> Exchanges frontrunning you and manipulating the market
This should not be a concern, just don't HFT your trades. Play longer time-frames (like a few months between a buy and sell); and don't use leverage.
> exchanges just taking your money and running
There are many established/regulated exchanges which have guarantees as good as the traditional exchanges.
> prices crashing without you being able to sell your assets
Maybe that's when you should buy?
> Cryptocurrency is NOT a market you want to be in.
I have been in this market for 6 years, and I was able to generate double digit yields every year (even on bear markets, actually these were the most profitable).
