So I want to know how to react to this market and what do Hodlers do in these situations. Do they Sell, Hold or Buy More. How can we Newbies save ourselves from FOMO in this situation.
Will be really thankful for your advices.
If you've held for so long and you're not that much greedy at all, sell. It's okay to sell at these moments but don't sell all that you have. If you have no plans of reaccumulating the sold BTCs that you have then still keep some and leave some for you. You'll never know how high it will be for the next years to come. You can take this as an example that the crypto wallet growth is continually rising.

So, if you have plans for your future, you should buy and keep the most while you can. It may not reflect for this bull run but look after 4 years again.
