I find the survey a bit short term focused on some of the questions

If you have some ideas or questions to add - feel free to post it here.

being some delimited to the last month

this will allow to find users who uses bitcoin in real life and distinguish them hodlers.

Those timeframes will capture a snapshot of information for those that are traders

yes, 'traders' (as I'm, for example) and 'users' like one of my friends who mines at home and pays for the phone or beer.

It also does not show long term behavioural trends, but only short term

we plan to do that once in a year, if it will be accepted by community. and that will give us the long-term profiling.

Additionally, the list of exchanges excludes some of the major ones, which seems odd.

please name them and I include them right now. (the problem with this list - it is too big)
