As Bitcoin is a currency as well as a payment of method, you can pay with Bitcoin. Bitcoin was established in 2008 and the popularity and the prices have been soaring since then. 2018 was the year when we saw its downfall. Due to Bitcoin, there are other cryptocurrencies coming up, too, like Ehereum, Litecoin, etc. Cryptocurrencies are very beneficial and can give huge profits if invested in smartly. Dut to their limited number, it will lead to an increase in the demand due to its rarity. There is also growth in the Gold and Silver trade which involves exchanging cryptocurrency for physical gold and silver. I have tried investing in cryptocurrency but I couldn't deal with how volatile the market was. I have been investing in the Stock market for years on which is no trouble as I had a stock broker to handle my tradings. Investing in bitcoins does a fair idea of the workings of it and when to pull out.
I hope I have helped you out.
