The long term winning strategies in crypto market start with good research work before deciding to invest in any project, which is key factor for the success of investment, because it can help a lot to identifying good projects which are fundamentally strong & backed by professional and dynamic teams .
Do that and you will find out a bitter truth which is that 99% of the projects do not have a fundamentally strong idea and is neither backed by a good team. Either those projects lack first mover advantage or they are trying to do something that is competing with a similar concept in the mainstream market. Mind you, any crypto project that tries to compete with a mainstream counterpart will always fail.
The next important factor is patience, which means avoid impulsive buying or selling and wait for the right time to take entry and exit to book good gains on your investment.
This is applicable to any aspect in life, but I guess in trading it brings in a whole lot of importance. We cannot have good returns from impulsive and reckless trading.
