The UBTC airdrop for LTC holders will start on February 11, 2018 and run for 48 months (until January 11, 2022). The block-height of the LTC snapshot will be the block at 12:00 UTC on the 11th day of each month. LTC holders can register their LTC addresses to claim UBTC on https://ub.com. Only LTC addresses registered there will be eligible for UBTC distribution. The ratio of LTC: UBTC will be 500:1 of 1/48th of the balance at the time of the relevant snapshot. For example, the amount of UBTC to receive if you’re holding 500 LTC will be 0.0208 UBTC that month (UBTC = LTC/500/48). If the next month you’re holding 1000 LTC, you will receive 0.04166666 UBTC. If you’re holding less, the amount of UBTC you receive is pro-rata.
