So buying for the long term is better. Ethereum currently has a downward trend. and you are better off choosing another altcoin to be able to take profits quickly. because the current Market does not have stability. all prices of crypto currencies are very high fluctuations. and I think it's better to use a scalping strategy to take profits.
I was not very lucky with short term trading but in this market hold is not working either? Can you explain how you do scalping and what coins are suitable for this currently? I agree that Ethereum is probably not the best choice for it...
