1. Do you think last ATH would be the highest We would see?
I don't think we already had the last all time high yet, there is still more to expect as the market continue to pump and make new highs, we already had $118,000 and it may lead to $120,000 or close to $130,000 and thereabout before we are done and enter into another season.
2. Do you also believe that bitcoin would touched $500k as people are already tweeted and share on this forum
Yes, but not this season, maybe after another season that we had halving, but for now, the maximum we may have is $150,000 if at most we are going high at all.
3. How do you think manage the market now that prices are soaring and altcoin aren't still making any new move to impressed their holds?
I have two thing to advise here.
1. There is season for bitcoin and there is also one for altcoins, maybe we are only in bitcoin season for this year
2. Altcoins are unpredictable, even as we speak, some are rising, while some are falling because they are not having utility use in majority, so if you cant afford the risk on them, then don't try invest on them.
