How bigs the blockchain currently? Want to play around with this a bit but my hd is near full. Any light wallets like electrum but for dash?
blockchain is maybe 4-5 GB
electrum wallet:
https://www.dash.org/downloads/Actually still < 1GB

Don't go by a bootstrap compressed file. The blockchain and chainstate directories are 1.44GB when running under in windows. Of course, if you add a 2million key wallet that bumps it up another 1.18GB, but a standard wallet is negligible in size.
