Main advantages for Avalanche are:
- less inflation
- better scalability (it is using Avalanche consensus)
- faster transactions (60 seconds for Polkadot and 2 seconds for Avalanche)
Less inflation is an attractive specification that is commonly used nowadays to attract investors. Do a value of one project, coin or token is defined solely by total supply and inflation schedule?
I believe it is not in the long run but in short time after launches, it can be used to make people believe about the future, lower inflation, higher price.
I agree people require for fast transactions but together with the speed, they need security and safety. 60 seconds for one block is fast enough in my opinion. The point is the size of block not how long one block is created in average. If a block can have huge transaction counts, it can meet the demand. Anyway, include huge transaction count into one block contains potential risks as same as too short block time.
