If it felt too hard to buy at 2k imagine how hard it will feel for people to buy at over 4k. I have heard too many people saying they're going to wait til the price drops by 30-60% before they will buy any, but that's what they were saying at 2k as well. I hope you will consider at least buying a little at a time here and there instead of completely staying on the sidelines until the 'perfect' time to enter. Keep at least most of it in a private wallet you hold the keys to.
