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.
This is very true, having funds, savings, or extra income while you're holding is needed, why? well because that would prevent you from selling the tokens you're holding in case you run out of funds, what I mentioned above will save your profits in the long run, therefore holding is a serious matter that needs a great decision making, if not, you'll just waste your funds and effort of waiting to nothing.
