Absolutely before buying coins, we have to do some research first so that we won't regret it later, but if we invest in bitcoin or ethereum, I don't think we need to doubt it anymore
Bitcoin and ethereum assets do not need to be doubted, but in investing these two coins I think you need to do enough market analysis. not only these two assets, all investments in crypto assets I think you need to do market analysis. it is very important that we need market movements in the upward trend for trade.
