Can you explain what is this about? Im not clicking random links from untrusted newbies...
Its some kind of a calculator that transform all your other coins value to bitcoin, and shows how much you can have if u convert it to bitcoin at that time.
Might be nice for someone thats holding many cryptos, but i think they know prices in their heads anyways since they are probably all traders.
Whenever ure concerned about some link, you can scan it on virustotal, or just open up another chrome windows in sandbox..
cheers
