Can DOGE be bought now?

To be honest, I find it hard to answer this question.

Because my cost is very low, currently I have several times the profit, I won't sell for now, at least until it reaches above 1 dollar.

And your cost is relatively high, there are also uncertainties in the short term, not having low-level chips makes you more passive, whether to buy or not depends on your own expectations.

If you really want my advice, it would be to buy those that haven't increased too much yet, or high-quality potential coins that haven't started yet. For example: wif, pepe, bome, apt, sui, etc.
