Question have you experienced this Weird feeling before after joining CryptoCurrency as Investor/trader?
Fortunately, no, I knew exactly what I was getting myself. I was able to gather a lot info about the cryptosphere before I started my adventure in this world.
And what you described is called ignorance. Not knowing how the crypto market works (difference from traditional markets, valatility, fluctuations, how unpredictable this market can be, how pump and dump works, etc) before even trying to buy or invest in a coin is simply wrong, even worse if you want to be a Trader, you're bound to either lose money in the long run or make big mistakes.
It looks so weird and the whole of market has been under control by some parties
Like who?There are many people in the forum that think the whales, miners and the exchanges are manipulating the price of bitcoin to benefit themselves, that is without a doubt a possibility, but I think people are just exaggerating they want to blame someone else for their losses when most of the time they are the only people responsible for their success or their failure.
