I might not have those 10 years because faucet could close before that.

The inflation rate in Hive decreases at the rate of 0.01% per 250,000 blocks until it reaches 0.95%. 250K blocks is about 8.68 days.

According to this post by Dalz, Inflation is around 5.5% this year. At this rate, in about 10 years inflation will around 1%

My recommendation is to take advantage.
