I'm buying BTC from an ATM so I can convert it into LTC.   The ATM's in my area of the US offer BTC only.   I'm having issues with Coinbase verification and really don't want to deal with them or any other verification exchange.  Particularly when I can just by BTC from an ATM and convert it to LTC faster.   

That's where I am at.  I need to know what to expect when converting.  I hear Changelly is not reliable and can charge up to 10 percent.  Shapeshift has issues also from what I read.  Is this your experience?  What can I expect?
