The best time to invest in crypto has already passed, now prices are not very high, but not the lowest. Now you can invest in top coins because they'll grow even stronger over time...
It's not yet passed as long as we can enter the market when the support is really weak. After the pump and the dump will come and this is the crypto cycle. We will have more chance to invest in crypto again.
The top coin will bring less profit to consider it has already had a lot of ROI.
