I've been looking to buy waves with BTC but all the websites i've found so far have mixed reviews so i'm not sure if i should use them..
Please let me know what website you use for buying and selling altcoins
you can directly buy in DEX
https://waveswallet.io or buy in any of the market listed in here:
https://coinmarketcap.com/currencies/waves/#marketsI'd suggest bittrex , livecoin and cryptopia and would avoid trading it in yobit.
All exchanges have their issues. You just gotta find one which has an active support and can help you out. You will read bad reviews on any of them but some are actually a good exchange.
