Cryptopia increased again the minimum for a trade ... what is going on with all these exchanges ?

Hello dear Steemians,

Yesterday 1.Jan I transferred small amount of money to Cryptopia exchange as I found out
that the Dogecoin market has a lot of trading pairs and a low minimum for a trade - only 10 Dogecoins.

Today the minimum amount for a single trade is 500 DOGE....

I liked the platform, the interface they have, the low trading fees and I moved money away from Bittrex and Bitfinex.
Both Bittrex and Bitfinex exchanges are doing whatever they want right now and recently introduced quite high
minimums for trades 15-20 USD depending on the trading pairs and also introduced a minimum for a withdrawal in some cases reaching up to 300 USD .... Now what is going on honestly ?? Not everybody in the Cryptospace is a whale with hundreds of thousands in their account .... What's the point of decentralization if at the end most of the exchanges are quite centralized and starting to serve only to the rich guys ....
I personally follow a trading strategy to diversify with many coins and a high minimum trade is killing me.

I am observing this terrible trend in the last 1-2 months and almost all exchanges are increasing their minimum trades, the minimum withdrawals, the minimum amounts for conversion of crypto to fiat .... it makes me very sad :((

What do you think about this ??
Does someone see the same trend ?
