# Crypto Trends

A summary of the crypto trends for the week.

## Downsides of Proof of Stake fast forward

Great editorial by Ben on the converging streams accelerating the move to Proof of Stake with a warning on the downsides.

## Berlin upgrade and EIP-155 replay protection

Deploying to Ropsten (upgraded to [Berlin](https://blog.ethereum.org/2021/03/08/ethereum-berlin-upgrade-announcement/)) using Truffle and users ran into the enforcement of EIP-155 replay protection:

> I've asked for help in the Truffle Gitter before filing this issue.

> Issue
> I have been working with truffle and experienced truffle migrate...

In the short term Alchemy and [Infura](https://community.infura.io/t/berlin-fork-and-strict-checking-for-eip-155-transaction-compatibility/2609) made a workaround to remove the enforcement.

Truffle are [working on a fix](https://twitter.com/timothyjcoulter/status/1369674454456967169?s=20)

NFTs NFTs NFTs

NFTs were in multiple articles in the mainstream press

> Artists have been dismayed to find their work ending up in the ‘control’ of others

Discussions on the climate impact of NFTs (another stream for Proof of Stake)

Pre-ERC721 cat projects were rediscovered over the weekend. (no links)  
(Disclosure I am friends with the team behind CryptoCats and I own a meta cat).

My suggestion is only buy art that you love, for a price that you can afford, and if you have rights, [hang it on your wall](https://medium.com/coinmonks/adventures-in-art-1b068ab0ebed) and enjoy. The price of any collectible can go to zero if no one wants to collect it any more. My art budget is about $50.
