I actually bought another 300 recently, not quite in your league but I did tell myself 'no more' a few weeks ago... but at these prices, you're right.
Mind you all of that went on PAL and steemmonsters cards! It's still Steem - but in its more evolved form as I see it.
I think HF21 has just got people nervous, that's where all the negativity is coming from.
Yeah, I thought no more when I reached 200k but at these prices...but o man...:)
