Note: This is not about how to identify good coins to HODL
This is about how you can be a good long term holder
1. You must have another source of income
Either in crypto space or outside crypto space you must have other source of income,there was a time when i used to rely on coins i hold for monthly income but most time they failed me because some altcoins takes more than a month to add value. You can learn trading or find a better job to get constant income for your daily needs.
2. Not all altcoins are good for long term holding
Some altcoins are too weak to have better value overtime,these coins only add value to price once in a blue moon,WHY?because the power of demand is too low and they have no working product,i belief that working product is what makes a coin have many more investors
3.HODL Only Altcoins With Real Use Case
There are different categories of coins with use cases,many use case are weak use case,for example using fashion designer to back a token is a weak use case to me because it means you can only use the token to buy the designer wears and many will call this a real use case? no it wont do very well.
Make sure that the real use case of every altcoins you hold will be very reasonable,the products backing them up must be something that is different and will catch the eye of investors,the usefulness must be outstanding .
4. Stay Updated Always
Opportunity comes but once as many know it,so always stay updated about crypto,read crypto news online and keep tracks on your altcoins so that you wont miss future updated or even token swaps,some altcoins i hold have already switched to MainNet and im glad i dont missed the opportunity,you can use blockfolio app to track your altcoins.
Altcoin season is what many are waiting for,even new projects are waiting for altcoin season to return before they get listed on exchanges,im sure of one thing and that is good things dont come easily,today is bitcoin turn to reign and one day altcoins will have its day as well.
I am totally agree with you because the same thing that I apply into myself whenever I am holding my crypto coins when I am certainly do not in need to use them or stocking them for good. The first one you have mentioned, I always certainly do to seek for another source of income because I never treat crypto as my main source of income and I know that I cannot always expect to have gain an income from it. Same thing applies to numbers 2 and 3 which I certainly sort out my alts into those that I can already give out and those that are good for holding into a longer period of time. The number 4 you have stated is the most important thing to do since we are into a volatile market in which every moment price changes, we must keep ourselves updated always for new informations regarding the price movement in the market.
