I always see market conditions, if the improved market conditions are short term it can be an option because it certainly provides convenience. but if the market conditions are not as good as now, whatever coins I have must be held long-term to get maximum profit.
Yes, I agree with your opinion that long-term and short-term trading depends on the market situation. In my opinion, currently the Bitcoin market is unstable and it affects the altcoin trade so short-term trading is highly recommended.
