Hej guys got today Stack of 650 RAIN but my weight fall from 22000 to 5000 is this normal? Cause now i need to wait 8 days for stack
Yes that is normal as the estimate weight can change all the time as more people start staking RAIN the harder it gets to earn stakes. You will need to try and build up your stack some more to compete with the other people staking. That is why the minimum amount to stake is around 5k as that should earn you a couple of stakes each week but again it would depend on the network weight.
now i have 4350 rain, but now like i said the weight was reduced so much.
if i get more RAIN will my weight grow faster?
I suppose so
afaik your weight is determined by the age of your coins * amount of coins.
you'll probably need to use coin control and combine your new amount into one big chunck.
I may be wrong though, got to confirm it.
