A small thread on the importance of using log charts:

Rs 100 of 1990 is not comparable with Rs 100 of 2021 in absolute terms

Similarly, price of a stock some years back may not be comparable with today's price in absolute terms.
For EG, SBI quoting at Rs 10 in 2002 is not comparable with SBI quoting at Rs 400 now

For a 100% jump in 2002, stock would have to reach 20 (which is just Rs 10 in absolute terms)

While today, Rs 10 in absolute terms is a meagre 2-3% move
We shall always calculate moves in % terms

For this reason it's preferred to use log charts, especially long term charts

Log charts calculate moves in % terms
Also, if a stock goes from 20 to 200 in one year, even then it's preferred to use log charts.

#RIL tgts are 2180 and 1820 positional over next few months if the high made at 2856 doesn't cross.

Not looking good.

So the cryptocurrency industry has basically two products, one which is relatively benign and doesn't have product market fit, and one which is malignant and does. The industry has a weird superposition of understanding this fact and (strategically?) not understanding it.


The benign product is sovereign programmable money, which is historically a niche interest of folks with a relatively clustered set of beliefs about the state, the literary merit of Snow Crash, and the utility of gold to the modern economy.

This product has narrow appeal and, accordingly, is worth about as much as everything else on a 486 sitting in someone's basement is worth.

The other product is investment scams, which have approximately the best product market fit of anything produced by humans. In no age, in no country, in no city, at no level of sophistication do people consistently say "Actually I would prefer not to get money for nothing."

This product needs the exchanges like they need oxygen, because the value of it is directly tied to having payment rails to move real currency into the ecosystem and some jurisdictional and regulatory legerdemain to stay one step ahead of the banhammer.
