I often reflect on this question: is staking a positive factor. I think rather yes, if inflation is not very big.
On the one hand, in any case, there will be pressure of new coins on the price. But on the other hand, I know that many people like to save and they like that their number of coins is increasing.
I remember in an interview a representative of either coinbase or another large similar trading platform said that they now have an increased demand for staking coins. Also, some exchanges began to develop this direction: polo (atom), huobi (there are generally a lot of coins - see huobi pool or wallet), binance (a lot), etc.
Therefore, I think staking is promising.
