It clearly IS competing against BTS as a sharedrop target and against BTS market value.
Actually there is one argument AGAINST using BTS as sharedrop target no-one brought up yet:
If you can recall PTS prices, what exactly happened after 28th of february last year?
BTS(X) market cap was effectively taken out of the PTS market cap at the time of the snapshot and the priced tanked big time.
Because BTS are used as collateral, this may result in ... you guess it .. a black swan (of course only if the airdropping market cap is large vs. BTS's market cap)
Also, IMHO, the goal of a snapshot is NOT to drive the price up (because it will go down again eventually) .... but to honor a community.
In my opinion, snapshots nowadays only make sense if you do them without further notice .. that way you
* do not drive price up
* prevent a price tanking at the time of the snapshot
* while you are still able to drop on your valuable demographic
Just my thoughts ..
