But lets assume if someone wants to invest in the long run, he can keep a regular check on the price only one time investment then what will you suggest Bitcoin or Altcoin ? I think Bitcoin should be the prior choice because of its remarkable performance over the years one can have more surety with Bitcoin than any other coin. Some of the altcoin may have bright future but there future is not clear also not sure that it will be as popular as Bitcoin, then why to take risk; simply invest in Bitcoin and wait for the jackpot.
