Bitcoin is just as speculative, if not more speculative than most of the other cryptocurrencies as well.
With Litecoin, Bitcoin Cash, I can send faster than Bitcoin.
With Privacy coins, I can transact privately.
With Ethereum, you can create tickets, and digital collectibles.
With Filecoin, and BTT, you can transmit data in a decentralized manner.
There's a lot of good projects with utility out there.
I'm assuming you're talking about memecoins used for speculation of course.
