Thanks for the list.

For someone not interested in trading but rather in exchanging FIAT - BTC - FIAT
there are a few options which could be beneficial like CoinEx with the cheapest transaction
fees and Huobi.

With the exception of Bitfinex and Poloniex there are others which are not that well known.

lists a few more, does anyone have any experience with:

Bityard
Bingx
Changenow
Waves.Exchange

As regards Changelly, I have heard of them before, how reputable are they?
