Long term HODLers usually buy the cheap in order to sell at the surged prices, there is no plan, just buying the potentially valuable coins for the cheap price will do the job. Longstanding price swings are more reliable than daily running behind the scalping on the crypto market.
Totally agree with you
The only thing I want to emphasize is number 3
3.HODL Only Altcoins With Real Use Case
There's no better tip than this one, people and devs write some beautiful whitepaper, launch a coin and try to sell to another people, but they can't asnwer the simple question: What problem you coin will solve?
They only want to lauch a coin, not solve anything, so it's not valuable in a future
The main problem is to understand which coins you have to hodl. We know a lot of situations when tokens gained so greatly that investors used to become rich people ( I mean really, serious investments here). It is very difficult to predict which of the projects will work and calculate the potential gainers.
As for another source of income, I totally agree here.
The shitcoins are the common problem of the crypto ecosystem, there is no exit for both the shitcoin owners and invested people. Knowing what to buy forces the investor to separate the reliable and counterproductive coins of the projects.
