Transaction charges Query

[Avinash]

Hi All,
I am a newbie in the field of crypto currencies. 

I just bought some XRP ( small amount) as test and incurred heavy transaction charges. 

Can anyone please explain if these charges are genuine or did i do something wrong?

1. I purchased some BTC amount from "bitxoxo.com" by spending the local currency INR.
2. The "X" BTC got deposited into my wallet in bitxoxo.
*** No transaction charges yet ***

3. I transferred the BTC FROM wallet A ( Bitxoxo) TO my wallet in gatehub.

--- Charge 1 ----
4. I was charged approx. 6% of the BTC (balance transferred) as " blockchain.info " charge!!! ( As per the support folks at bitxoxo, the charges were levied by blockchain.info as they maintain record of every transaction)

---Charge 2 ---
5. I tried to exchange my BTC to XRP at gatehub. I was again levied 0.2% XRP as transaction charges.

# Are both these charges genuine ?
