What is the best cryptocurrencies exchange (reliable, cheap and decentralized)?

[erotavlas_turbo]

Hi,

I'm new of this forum and I'm sorry in advance if I make some mistakes on posting this message. I'm investigating about how to buy cryptocurrencies. During my search, I found many exchanges with many important features.

Correct me if I'm wrong, but I found that the best way to exchange cryptocurrencies is by using shapeshift that requires only network fee and so it is cheap, moreover it is decentralized and finally it is also reliable since it does not require any account and deposit. Hence, my problem is to find a reliable, cheap and possible decentralized exchange that allows to exchange fiat currencies into cryptocurrencies. I found many exchanges. Someone has an input investment barrier as bitfinex (10k $) other as bittrex do not allow new users.

Finally, I found coinbase, changelly, cex.io, kraken and paxful. My first problem is to choose one that is cheap. For instance, changelly requires about 10% (5% changelly and 5% simplex) of fee plus network fee. Coinbase reports the following fee 1.49% for standard and 3.99% fee for instant buy fee. Similar fees or worst fees for the other on the list.

Could you suggest me what is a cheap way in order to enter into the cryptomarket? If it is possible it would be better also a reliable and decentralized way.
Thank you

You have IDEX or OpenLedger exchange If you have no plans to use fiat. and If you want to trade with fiat, you have Bitsquare.io. It's worth mentioning that decentralized exchange have a lack of coins and liquidity as not a lot of people use them.
