I want to buy WAVES can someone please send a link or something on how to buy it and what is escrow?
You can buy some on NXT Asset Exchange:
https://nxtforum.org/asset-exchange-general/bbwaves-(waves-gateway-asset)/This offer is without escrow but owner of the asset (me) has good track record, you can buy in small chunks and redemption is available already.
Current price is at 75 NXT ~ 0.00087 BTC per WAVES.
