It is unrealistic to buy the bottom and go long now. BTC is neither high nor low. At least it will start to consider layout when it starts at 6w1.
The altcoins bought when BTC is above 7w will not be recovered until September. During this period, there will be a sharp correction, which will mainly kill long orders.
The current altcoin price is likely to be halved. Long orders are just giving away money. The risk of going long is greater than that of going short.
