I think it will still be profitable but I don't recommend buying now. Before you do, at least wait for a dip or dump to occur. In the case of ETH, I think it is still a good time to invest if you plan to old it for long term. If you are looking for short term profit, you better look into other alts that have potential to grow because there won't be much short term profit on btc and ETH now. If you are still unsure that it will grow more or not, I would leave it up to you to invest into crypto or not its not my loss anyway if price goes down it's yours and for this reason you have to make the final decision yourself.
