Merits and Demerits of Current transformer secondary winding turns

Less turns = higher secondary current
More turns = less secondary current
Where do you take the magic number 100 from? You can have current transformers with widely varying turns ratios, depending on your application.

have designed my own CT(ferrite core coil) with just 30 turns, bcuz of lesser primary current about 0.1A, does it have any drawbacks in long run. thanks for your reply
What are you thinking of?
If the transformer and the circuit surrounding it are designed properly (i.e. with respect to impedances, wire gauges, current flowing etc.) and works correctly, which long term effects would you expect?
how to calculate impendance by no of turns, can u give me an example of it. thanks
You will need the parameters of the core. The datasheet typically states e.g. the AL number which you can use to calculate the inductance from the number of turns.
A general description of the calulatiob of inductances is e.g. here.
