@burnpost is slowing down the rate at wich the debt ratio decrese

But this too is not necessarily true. The market cap is the product of price and supply (in existence). Price is the result of a balance between supply (sold or with the apparent prospect of being sold) and demand.

@burnpost reduces the rate of growth of the supply in existence but also reduces the supply being sold or with the prospect of being sold, therefore has a positive effect on the price. Now, again, market cap = total supply times price, so with less supply and a higher price the effect on market cap is unclear and depends on the magnitude, so it ends up being subjective.

Again, apart from the immediate burn, @burnpost retains half of the rewards for a long time, which increases the price.

I do think you raise one good issue here, which is that it would probably be better for @burnpost to power up all rewards under these conditions and burn later (as it already does when SBD is overvalued), to avoid the immediate negative effect on numerical supply altogether. I'm preparing some updates to the @burnpost template including a new FAQ and I will probably include this update to the policy. If I do I will credit your input.

Now this part is interesting... so instead of presenting counter-arguments about my arguments you go for a ad hominen argument

Guilty as charged (though I did, in fact, present some specific corrections). Instead of spending 5x as much of my time addressing every error and misunderstanding your post, I summarized that it is overall of poor accuracy and quality, which hopefully helps avoid spreading bad information, or at least raises some alarms and gives people a reason to be skeptical and do their own research. I also don't think inaccurate and misleading information should be rewarded. Sorry.

bringing up to light a discussion

Bringing up a light (which I agree is a good thing) can be done by asking questions or making narrower observations which are actually accurate. It doesn't require, or even benefit from, putting out confused, misleading, and incorrect information.

So i don't think these arbitrage bots actually have any real effect on the price.

They don't. and I never claimed otherwise. What I claim is that they transmit supply and demand imbalances between exchanges keeping the prices in line, so it doesn't matter (beyond some tiny slippage effects) which particular exchange is used. Buying is buying. When you buy (a non-trivial amount of) SBD, you increase the price of SBD, and increasing it on one exchange increases it everywhere.

I'll get back to you with one or two of the account names for arbitrage bots. It is a bit tedious to look for the blockchain history to find them, but I know they are there, since I used to run a market-making bot on the internal exchange which traded with them very frequently.
