2023: Can be considered the explosive phase of layer2 in vertical segments (only 1 segment), too many vertical segments to meet the demand x10 x100 of the bull season while most of you still see the market is not yet bull. So the fragmented layer2 is at risk of falling into a deadlock of lack of users, lack of liquidity, lack of costs, pressure from investors. There are also many solutions such as cross-chain bridges to transfer assets, modular to separate functions, or restaking to add liquidity,... but Ethereum itself or someone else will build the so-called unified web3 world. Some parties currently add blockchain associated with AI to have a bit of a trendy flavor. Also in 2023: Bitcoin's leader rises to give birth to children who compete directly with the group of disciples with products such as BRC20, Ordinals, Runes and currently there is layer2 Bitcoin, sidechain, Fractal is also worth noting, ... the idea of ​​restaking is also the basis for adding liquidity to the layer2 Bitcoin group.

What trend will the crypto world race in 2025?

2011: Litecoin appeared to prepare for the Bitcoin clone wave and Litecoin was the first successful clone. Bitcoin is Gold, Litecoin is Silver, in addition, there will be copper, iron, zinc, titanium, rare earth mines, etc. -> in general, the trend of miners exploded 2 years later in 2013.

2015: Ethereum appeared to prepare for the ICO wave, Ethereum can be seen as the ancestor of ICO on crypto successfully raising capital and promoting other brothers to compete to raise capital to build the so-called Ethereum killer -> the trend of layer1, the blockchain layer1 killer exploded 2 years later in 2017.

2019: Can be seen as the explosive phase of building layer2 after the Ethereum killer group did not operate effectively, even could not kill any skin of Ethereum, so brothers decided to surrender and build around Ethereum (Polygon, ARB) or clone Ethereum without having to do anything hard (BSC) -> 2021, the trend of layer2 later appeared in series and the problem is that too many layer2 will be fragmented and have poor liquidity, building a layer2 smartchain but nothing runs on it (for example, NFT boss blur built Blast specializing in NFT but it also failed). ARB and Base always attract users by using ETH so that users from Ethereum can easily access it.
