What Are Liquidity Pools?

Liquidity pools are place to pool tokens (which we sometimes call liquidity) so that users can use them to make trades in a decentralized way. These pools are created by users and decentralized apps (or Dapps, for short) who want to profit from their usage. To pool liquidity, the amounts a user supplies must be equally divided between two coins: the primary token (sometimes called the quote token) and the base token (usually ETH or a stable coin).

How many times have unique wallets increased liquidity in the past week?

In the past week (2021-12-20 - 2021-12-26) 2144 addresses provided liquidity to LP on Sushiswap. On the other side 943 addresses removed liquidty.

Most of these addresses provided liquidity only one time and there are only a few addresses which have done this more often. Nearly all, 1816, addresses provide liquidity only one time.

How about decreased liquidity?

When we look at the addresses which remove liquidity, we can see a similar behavior. Most of these addresses, 873, removed liquidity only one time.

What other metrics might affect these behaviors?

From my point of view, another important metric is the price chart. When we compare the price chart and the liquidity adding addresses we can see a very similar characteristic. As the price increased also the number of addresses (adding liquidity) increased.

If we compare the behavior in another time unit, we still see an identical trend in both charts.

Conclusion

Again, what we can see here is, the price chart always influences the behavior of investors.
