American mining company Riot Platforms has reduced its BTC reserves by selling some of the accumulated coins amid market volatility and the approaching halving.
Such actions are often interpreted as:
an attempt to take profits,
reallocation of liquidity to cover expenses (e.g. electricity or equipment),
Reaction to changes in yield after the halving.
Riot is one of the largest publicly traded mining companies in the United States, and any changes in its strategies can affect market expectations.
