That depends on what you mean, bitcoin has proven to be a great investment since the beginning so the answer is a clear yes as I think that any one that buys now will obtain great profits during this year, there are other good coins like ethereum and the like, however there are some awful investments, one of them is XRP, the coin despite the incredible bull market we have went through was not even close to reach its ATH and there is a pending case against it, tether is also not a good investment since you are basically holding dollars with the added risk the company behind it could disappear.
