Blocktrades enters the steem power delegation market with much cheaper rates

Blocktrades entered the steem power delegation market a few days ago and it is offering steem power delegation at much cheaper prices.
Blocktrades has initially started two delegation periods which include 30 day delegation period and 90 day delegation period.
The good thing about leasing steem power from blocktrades is that you can buy steem power with every currency that is listed on https://blocktrades.us which saves you from additional fees you pay to trade between currencies.

I made a collage of these three screenshots which I took from their website which shows the three major cryptocurrencies are accepted and besides these three there are a few more.

Now let's see at what price, blocktrades is offering steem power delegation,

You just have to put the amount of cryptocurrency you are willing to spend to buy temporary steem power.
Let's say I have 10 steem and I want to buy steem power for 30 days. As you see, it is delegating 493 steem power for 10 steem.

Now let's see the price at which the rival minnowbooster is offering the same amount of steem power for 30 days.

The same amount of steem power costs you 4.5 steem extra if we take 30 days into consideration.
That means you are saving $4 approx if you buy from blocktrades.

For 90 day delegation period, I put an amount of 100 steem on which blocktrades is giving me 1882 steem power.
On the other hand, the same amount of steem power for the same period of time from minnowbooster costs a whooping 63 steem extra.

Moreover blocktrades is promising that on renewal of previously delegated steem power, users will receive additional discounts.
I think more people will switch to blocktrades now and in order to be competitive, minnowbooster might have to bring the prices down.
