Welcome to crazy run of BTCUSD, many people are claiming this bull run as manipulation either for price increase or for closing short position. Well as per us it is none of them, also no technical indicator will make any sense right now as market is driven right now with world's geo political sentiment instead of indicators.
No new people have joined BTC bandwagon , then from where this much money is coming if it is not manipulation? Answer is simple from smart money. Due to china-usa trade war going on there is very high uncertainty among investors(smart money) regarding currency and further companies prospect. Currently , they are trying to play safe by putting the money in Cryptocurrency as they dont know what steps china and usa are going to take.
Untill the cloud of trade war is over , we can expect the rise in BTCUSD price or better more smart money coming in crypto world. But be aware, this money is not going to stay here for long , as soon as trade war gets over, smart money will also leave crypto world.
