There are two types of crypto key opinion leaders (KOLs) or, in other words, influencers - micro and macro:
Micro-influencers are usually very niche. For example, they can focus only on NFT,
DeFi, Metaverse projects, or crypto trading. They have a relatively not so extensive followers base. However, they provide an extremely high engagement rate.
Macro crypto influencers tend to tweet about anything on the crypto market and are usually represented on almost all social media platforms. Compared to micro-influencers, their audience is more significant, which gives an excellent opportunity to promote your brand on a broader scale.
