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.
