First of all your choice about OPtimism and Immutable is good choice in my opinion layer 2 is on the rise nowadays but the bitcoin price is not good making this is not the good moment.
but what he wanted to learn is the target price in which the best timing to enter .
Im gonna share my opinion though the price of bitcoin now is testing 26K support or 100 EMA and it seems the price reject at that point. When bitcoin price reject for couple of days and show bullish I think that is the right call to buy altcoin like Optimism.
Hope that those coins will truly follow the movement of bitcoin
for OP to gather what he is targeting to earn.
The graph shows the resistance but yes we keep holding about that price and maybe 26k isn't coming any time now or soon.
If you look at the chart the yellow line is previously a resistance and now turning into a major support although is not there yet. you need to be carefully since the price already broke the 200 EMA and I would say the good entry point for OP is $1.2 and take profit on $2
while that seems to be close, why not purchase at 1.3$ instead of waiting more since there is only a 10 cents difference .
