That's right. In the past several years, Bitcoin has that trend of being dormant for months at a time before surging hard to double or almost triple its value. That's why many people would tell you that when you are investing mainly on Bitcoin patience is always key because return of investment may not come for about six to nine months like last year. So, that's why it would be better to have another medium of investment in your portfolio such as those good altcoins instead of juts being passive for most parts of the year.
