Yes, bitcoin has been declared as a speculative asset but Gold is $1300/ounce and Silver $17/ounce.
Bitcoin at $2,000 is also high. What is the point of mining cost of one Bitcoin = $5,000 when mining cost of gold in $500/ounce ??
Bitcoin is crptyocurrency where you can earn money because of it, people classify it as an asset where you can profit. I think bitcoin is a great asset because of it's popularity and higher value in the market.
