What are the top gaining cryptocurrencies by market cap?
I'm curious to know, which cryptocurrencies have been seeing the most significant gains in terms of market capitalization? Is there a particular sector or technology driving these gains, or are they a result of broader market trends? Also, are these gains sustainable, or could they be subject to sharp corrections in the near future? I'd like to hear your thoughts on this, as an expert in the field of cryptocurrency and finance.
