Too Much sales, is this a bad sign?

So, I run this Saas Feedspace.io. We launched 3 months back, We had two problems, traffic & relevant users. We are just starting so I went ahead and prepared an Appsumo launch. This Appsumo launch is supposed to get us visibility and early traffic, if people can't comapare us to our competitors, we can't even get sales. So i went ahead and figured out LTD plans from $49 to $499 Lifteime. I thought I should reach out to early users and offer them 50% discount on buying LTD before Appsumo Launch, I assumed that I might get some 3-4 sales before Appsumo launch on 12th feb. But boy, I was wrong, I posted in 2 facebook groups and we closed about 52 LTD sales within 48 hours, The users I spoke to mentioned: gathering of reviews from all over the web Audio reviews potential and high collection rates Lifetime deal at discounted price were all big reasons for them to quickly buy the LTD and call it a no brainer. I am not sure, is this a good sign? I mean once I stop LTD will we have any MRR growth, I mean have a whole SEO and Performance plan for signups but I am unsure of MRR numbers, I didn;t expect this much sales from a simple post. 10 users directly asked for the $499 version and started using as well. Can someone offer some advice here? I launched SmartTask.io before this one Appsumo, we sold really well at that time, this is my second Appsumo launch!
