it's very good for technical analysis. and have something in common in 2016. If it does, we will see an increase in December and January. but we also cannot be sure that it is strong support. because in crypto currencies, anything can happen. I hope this support is strong. and re-form the rising pattern until halving is finished and makes the pump high like in 2017.
I doubt that we will see a pump similar to 2017 after the block halving, it will take months or even years if we are going to see another massive pump.
I am sure that it will happen again after a long time, 5 years or more. Block halving is a great factor for saying it so, we might see a massive pump again in 3 to 5 years at least. But bear in mind that bitcoin is not the only cryptocurrency we can enjoy with, there tons of crypto to play with the market, Diverse as they said.
But it's good to see the comparison chart, at least we have something to look at and people will find reason to invest on bitcoin because of the supposedly similarity between the two. But the moral here is that despite some similarity there could be a lot of difference and that the pump might not actually happen in 2020 but in the following years to come.
As a matter of fact people don't really seem to base on charts but on the current trends, and they will just know it afterwards. Investing isn't that hard but the courage of investing is pretty hard to get especially on beginners who is not confident enough to go in the fluctuating market risking their money. What I think the key here is that, don't expect that much or do not be overconfident because of what you have seen online. Just be chill and positive.
