Yes Bitcoin is the first kriptocurrancy currency that began in the year two thousand and nine. Because of its specific features, its network and security systems are found to be very strong and its legitimacy has been guaranteed by the global community for such investments. After the introduction of Bitcoin there are various alternative coins also exist in the market with similar configurations. I think other coins will follow Bitcoin to support the existence of Bitcoin itself so that Bitcoin will remain the benchmark of the coin market and become the major coin in the market.
