When there are technological innovations in the cryptocurrency space, such as a blockchain technology upgrade that improves transaction speed by 50% and reduces fees by 30%, it can significantly increase the cryptocurrency's market competitiveness. This may attract 20 - 30% more users and investors, driving up the price by 15 - 25%. If a new consensus mechanism is introduced but faces technical problems, like security vulnerabilities or low network participation, and has low market acceptance, say only 10 - 20% of the community adopts it, the cryptocurrency's price may drop by 30 - 40% as investors lose confidence in its long - term viability.
