I actually work in the computer vision field right now - what is it you want to do? Optics, AI, odometry,...?

hello fren. Yeah, my opinion didn't change since yesterday.

I've written a trading bot for Bittrex but it didn't make much more than when holding. Then again, it was crypto and it was 2017.
Automation is generally not a meme, so if you got the right tools, I'm sure it's valuable.

For what? Stochastics as the mathematical subject is burried under a deep pile of math that might take you a while, while inference is sometimes more like physics than like math - you interact with the world and there's no writing down the axiom and coming to a conclusion which cost function is -the- right one. Both are great subject and overlap significantly.

You'd probably not know if it was broken :)

On a related note, I wasn't gonna shill my channel here right away, but just last week I had uploaded a 2h video on how ECDSA works, and in particular with bitcoin raw transactions
https://youtu.be/YZafZ3Rvd8I

Neat.

I'll take the moment and shill my youtube channel

I can do python scripting right away, although I'm also not afraid of the compiled OO ones.
As I've written above, my idea so far is contrarian trading on BTC-ETH:
You buy into an ETH dip and as it goes up by pGain, you sell (1+fee)/(1+pGain) and accumulate the rest.
E.g. Say fee=0.25% and ETH went into a dip at 300$. There you but 1 ETH and wait till pGain=2/100 or 2% meaning it's up at
(1+pGain)·300$=306$,
and now you sell
(1+fee)/(1+pGain) ETH
i.e.
0.982843 ETH
which at 306$ is 300.75$.
So you get your cash back and gain 0.017157 ETH.

My idea would be to have a Baysian update on the expectation running how the next candle will look like. Your Python routine has 1 minute and you can, at each point in time, look back at n past events. At the end of the day, you can add coefficients in the algorithm and determine the "would have been best" parameters by finding what would have been the optimal strategy.

In this video I'm gonna attempt to explain some ideas behind a blockchain to you. I'll try to do this by playing with a system that shares some mayor similarities with it.

A blochchain is a seqeunce (the "chain") of blocks (data structures with information entries).

For cryptocurrencies, the information entries are data like "Alice pays 0.34 BTC to Jerry", i.e. some string/sentence of information , although the nature of the information is not so relevant for the blockchain as such. It could also be something like "Next friday I should go buy milk".

In this thread, we could as information any 3 letter word. Like "man" or "bob".

I'll introduce a very cheap kind of almost hasing. At the bottom we have a list of how to translate letters to numbers. Given two letters, we gonna have one act on the other by adding the numbers and translating it back. Examples
* b=2 and f=6. Now 2+6 is 8, which is associated with h. So we say b+f -> h
* j=10 and c=3. Now 10+3 is 13, which is associated with m. So we say j+c -> m

a = 1
b = 2
c = 3
d = 4
e = 5
f = 6
g = 7
h = 8
i = 9
j = 10
k = 11
l = 12
m = 13
n = 14
o = 15
p = 16
q = 17
r = 18
s = 19
t = 20
u = 21
v = 22
w = 23
x = 24
y = 25
z = 26
We're gonna say 27 maps back to 1 and 28.

We gonna have two lines. One "information line", and one "previous hash" line. On the first block, there is no "previous", so I'll arbitrary set it to "ccc".

Finally, given any three numbers, I'll do some WORK by multiplying them together. For example, ccc translates to 3 3 3 and 3*3*3=27.

I'll now start the block chain, and my first information will be "man"

BLOCK 1:
>"man"
>ccc, 27
->
>pdq

To explain again, m=13 and c=3, so the first hash letter is 16, which is p. And so on.
My second information is gonna be the word bob.
For the "previous hash" line, I obviously take the hash from the last line.

BLOCK 2:
>"bob"
>pdq, 1088
->
>rss

Okay, now the block is on.

Give me a 3 letter word!
