So excited to see Bitcoin coming down to $59,000 after waiting for a long period of time to see such opportunity to buy more Bitcoin, I just bought 4.5 Bitcoins at the present price which am feeling happy for at last am among the new Bitcoin whales at the moment.
Since you wish to become a whale, then you have to add some more to finally belong to them (whales). Having 4.5BTC in your control is big enough for normal people, I believe you have the capacity to buy more.
But for me, even if I have a lot of Bitcoins, I'd never tried to become a whale and manipulate that market as it never works this time. For it is no use anymore and instead of planning to have that position, it was good to live like a normal investor.
All I can say is that you need to be careful with your keys, holding huge funds is the primary target of hackers. I hope you will not be their target for now...well, congrats.
