When you talk about cryptocurrency, the first thing that goes into your mind is bitcoin
You can talk about yourself but should not talk on behalf of others. Different people have different mindset even in cryptocurrency investment.
my advice to crypto investors is invest where you feel safe, which is bitcoin, when you buy bitcoin, you don't just buy an asset, you also buy peace of mind.
When anyone join cryptocurrency market, it is a start of journey with mixed feelings: confidence, uncertainty, panic, fear, doubt and more. If anyone can feel safe since a first day of participation in this market, I don't believe it.
the market can be sometimes crazy that even the dip will scare you for the value of your asset, but bitcoin will always be bitcoin, it always stand strong, it doesn't fail to rally back an most times even better, unlike most alt that wouldn't gives you peace once the dip is very strong, I don't really know if anyone else feel the same way?
You can talk about it as a lecture from paper book but you don't understand it if you don't actually experience the market long enough to train your emotion, psychology and being well adaptive with this volatile market.
About past and future of Bitcoin, first let's see its past "Bitcoin is dead" times.
From past stories, it looks like Bitcoin has become stronger with time, with less "Bitcoin is dead" Obituaries. About future, you can make your own speculation but please don't say like "Invest in Bitcoin is zero-risk" as it is not true.
