There's a lot of article you can read online, they have different opinion on the market, just don't limit yourself to one article or a bullish articles only, try to read articles that are saying negative about the future of bitcoin so you'll be able to weigh things because making a decision.
if you believe on the future of Bitcoin and ETH, you'll never be late, even if you buy them again at peak as when these two will be successful in the future, it will eventually break its ATH.
I strongly support that statement. in fact, until now, I also want to have a very large amount of bitcoin and ethereum. however, there are currently issues that president Kim Jong Un will sell his bitcoin and have an impact on crypto prices. if you believe that, maybe the price of crypto will go down once more, but if the prediction is not correct, you will miss the train. however, I feel that at the moment the price is quite cheap. I am sure in the future many things will support the rising price of bitcoin and ethereum
