This is a worrying red flag about a company: adding ETH or any shitcoin to their treasury denotes their poor understanding of crypto and finance in general, trying to attract investors money, to the short term benefit of shareholders, rather than the long term value of the company.
Sharplink of other similar firms shall be avoided.
When big companies invest in sheet coins like Ethereum, the price of sheet coins may increase for a short time, but it will not be a long-term one. Maybe companies will enter the market to make a profit for a short time and they will leave the market by making a profit by artificially increasing the price from the market. In Bitcoin, I don't think any sheet coin will ever be as stable and widely accepted by people as Bitcoin.
So far, many sheet coins have come into the market that were very hyped for a short time, but they quickly drove investors crazy and were removed from the market. It can be assumed that big investors will never hold Ethereum or sheet coins.
Although they do invest in these tokens, it will be for a short time.
Bitcoin is the most reliable and secure coin that maintains the correct value of assets during inflation and is the most acceptable coin by all people.
