Trust me, create a cold wallet and start to hold now. It's not hard.
A hardware wallet is going to have to suffice for me, and unfortunately I don't have a lot of bitcoin stashed in it--but that's where it's going to stay until at least well after the halving. I don't plan on selling or trading any of what I have, but I'm also not confident that the halving is going to bring sunny times to the crypto market either. But I'd rather have some bitcoin saved up just in case the market starts to go buck wild as it did leading up to the end of 2017.
Not that I'm hoping 2017 repeats itself, because the crash apparently shook a lot of bitcoin investors out of the market and they never came back. I have a feeling, though, that if we have another clear-cut bull market starting, those dropouts will probably start to get
very interested in bitcoin once more. But we'll see. There's still a lot of time before the halving.
