How do they put several bitcoins into a block? I recently read that there is an auction to sell almost 24,000 bitcoins, and that they have put them in blocks, each containing 2000 coins. What does that mean to put 2000 BTCs in a block? Can somebody clarify please?
By block they are not referring to the blockchain. They just mean that the 24,518 BTC will be divided into 12 different lots (or blocks) with each auction containing about 2,000 BTC.
