I'd say that the domains that get high bids are the dropped ones usually. Because the people who bid on them initially may have backordered them.
It's domain discovery. There's loads of places on the internet that display which domains are about to be deleted and will drop. So people know DropCatch, and if they think a domain has potential, they go and place a backorder on DropCatch.
If you study some of the top domains, you might see that some of them have multiple bids at 59$.
Which means that they all had backordered this. I've noticed this happen when I backorder and others backorder.
So first, it's domain discovery. People on various platforms see potential, and place backorders. DropCatch catches the domain (sometimes loses it), and then due to 2+ backorders, the domain is thrown into a 3 day auction.
When it's in a 3 day auction, the number of bids is sometimes high depending on the number of backorders initially.
When the bids are high, people are able to filter by number of bids, by the highest value, etc... So they discover some of the best domains are now on the market back again. And thus bid on it.
Like I said, some domains have several backorders. So all of these people would already have a vested interest in the domain name to purchase it. - Leading them to outbid their competition. - They did backorder it remember.
So let's say someone a private seller decides to group his contacts to bid on his domain to cause the number of bids to go high - in an attempt to be "discovered" on DropCatch, well..
The organic bidders on dropped domains had a vested interest. They have a definite reason to bid/outbid to obtain that domain.
So simply boosting the bid count might just be a complete waste of time and resources.
The main thing is, if you want top sales on Dropcatch, do this:
1. Find an audience - a market - that would really want a particular domain.
2. Find the domain that that audience would really want
3. Put it on Dropcatch (might not be the best idea), on Dynadot, on your own site (best imho), put it anywhere - then go to the market that really would want it, and pitch it to them.
That's real selling -i think.
Of course if the domain on DropCatch is super good like Fruti or Navio (both sold recently) then those are definitely good names. And they might definitely get caught in a DropCatch bidding frenzy. Just watch the top domains towards the end of each auction cycle. - You'll be able to notice which ones are topping the bidding frenzy.
