Buying in parts could be a good idea if undecided.
For many investors, this looks like the bottom of it and I feel them as the purchasing urge may be coming. So I suggest buying in different parts to avoid full regrets. The bottom of Ethereum at the last bear was $230 if I remember correctly and I doubt it will come to that point again.
$1,100 for Ethereum (time of posting) is still too far from the last ATL but it's in a good position for buyers who are in a rush. You could be in the middle of everything and if the plan is long term then it's a good buy.
Agree! if you are planning for long-term investment, if this asset serves as a preparation for your retirement that kind of mindset will allow you to wait and hold, there are many other alts that you can pick and like what you are suggesting if you look from the last time low there are still chances that we can experienced this same scenario and then again the market will return and bring the strong bull back on track.
