Seed: from $100k, but the figures are arbitrary. VC come in. At this stage, often you have a prototype. The hypothesis and business model are being tested.

Series A: Checks can start from $N million. The hypothesis is proven, the product earns. Further scaling

Series B: The company is developing successfully and finances are needed to fight competitors and expand into new markets.

Series C: Everything is clear about how the company makes money. This round marks the start of the company's preparation for an IPO.

Observation about cryptoventure #1. Many VCs choose to invest in infrastructure projects. At the same time, there is a dilemma, what is more primary infra or content? Some tier-1,2 VC "do not disdain" to invest in content-related projects. The same crypto games, although they are aware that their business model is unlikely to be successful. Why? Perhaps the answer lies in the fact that in new niches such companies also have to solve infrastructure problems.

Axie Infinity created a sidechain that way when Loom Network let them down. Then they created a wallet and even a DEX.

Observation about cryptoventure #2. Don't blindly follow the funds' investments: You don't know their strategy, timing, etc. other conditions. Finally, it can be a strategic investment to take over the market and match a team with another in their portfolio.

Observation about cryptoventure #3.
Crypto games are an excellent tool for onboarding users, followed by developers in infrastructure investments. Having in your portfolio L1 or L2 with a check from $50M-$100M, why not leave $1-$2M in crypto games that have a viral effect and increase the value of the main investment. Stepn and Axie Infinity proved it. How many people thanks to these games have installed wallets for Solana, Ronin, Metamask, began to use USDC and NFT. Thanks to this, the ecosystem and the number of users in blockchains has grown.
