This morning I saw an article where a guy made a simple calculation through Google trends about HODL strategy, and it showed that call to HODL used less and less from February of 2018. Popularity of word Bitcoin and crypto currency is also falling down.
Why it is so? Do not people believe in Bitcoin and it's bright future anymore?
No matter on such tend I am going to HODL my founds till bitcoin will not come back to 20k$

The HODL strategy is only effective to the coins that have potential in the market. Before you hold a coin, try to identify first if the coin that you have is promising or not. The HODL strategy is not good for shitcoins.
