my friend, every market is manipulated, not only the crypto market, that´s some thing quiet normal in the world of trading, if its comodities like silver or gold or orange juice or even stocks, options and futures.
Big money from the institutionel Investors, banks and states is looking for gains in every second of the day so its normal when there are shifts from dollar to BTC or from Gold to dollar. the amount of money what is circulating around the globe is so huge that you can manipulate everything you want to if your one of the guys who own or manage that money.

So you just have to look for strong ups and strong downs in the price of what you are willing to invest in and then buy if the price has a spike down or on the other hand side sell when there is a huge spike up, you may not reach the top or the lowest point but your gains will be better than 80% of the market participants ;)

And by the way maybe its good to concentrate just on one coin, the original if it should be crypto, why chose cheap copies for your hard earned money, you don´t look alone for some gains but also for a usefull coin for saving your purchasing power what declines every day or hour in your fiat currency.

So it needs a wise and smart decission and after that you will have a lot more fun in the coming years than all the others who stayed outside and belive in the mantras of their governments ;)
