In the context of blockchain and cryptocurrency, the allocation period refers to the specific time interval in which token sales or initial coin offerings (ICOs) occur. During this period, investors have the opportunity to acquire tokens at predetermined prices before they are made available on the open market. This phase is critical for projects seeking to raise capital and for investors looking to secure early access to potentially valuable assets. The allocation period can vary in length and may influence the investment strategy of participants based on market conditions and project timelines.
