They are on to you 
Over the last few hours the hack became phishing attack and then API attack.
All unconfirmed at the moment but at API attack I was looking hard at my phone that uses to Blynk to pull data from the exact Exchange that is under attack (and where my stash is). Seriously.
There’s a lot of “Bitcoin Server” thefts in the news just lately, here in the UK and Iceland to name a few …
That’s a new world… Not sure if I ever gonna like it…
but it’s coming …
And finally the Touch sensor … 
#define BLYNK_PRINT Serial
#include <WiFi.h>
#include <WiFiClient.h>
#include <BlynkSimpleEsp32.h>
char auth[] = "";
char ssid[] = "";
char pass[] = "";
int threshold = 40;
bool touch1detected = false;
bool touch2detected = false;
BlynkTimer timer;
void gotTouch1() {
touch1detected = true;
}
void gotTouch2() {
touch2detected = true;
}
void setup() {
Serial.begin(115200);
Blynk.begin(auth, ssid, pass);
Serial.println("ESP32 Touch Interrupt Test");
touchAttachInterrupt(T2, gotTouch1, threshold);
touchAttachInterrupt(T3, gotTouch2, threshold);
timer.setInterval(1000L, myTimerEvent);
}
void myTimerEvent() {
if (touch1detected) {
touch1detected = false;
Serial.println("Touch 1 detected");
Blynk.virtualWrite(V5, "Touch 1 detected");
}
if (touch2detected) {
touch2detected = false;
Serial.println("Touch 2 detected");
Blynk.virtualWrite(V5, "Touch 2 detected");
}
}
void loop()
{
Blynk.run();
timer.run();
}

I told you nothing worked on that MCU.

Touchy subject 
… now use an ESP32 to connect an UNO to Blynk and watch the tears (or pitchforks) flow from Cyprus.

@mohan_sundaram Derbyshire / South Yorkshire border with elocution lessons as a youngster as school had me down as a future newsreader 
Ignoramus Mohan wants to know how you tested the touch sensor. What additional hardware did you use? How many pins are touch sensor enabled?
No extra hardware required or just a jumper wire off a pin perhaps…
I believe there are 10 pins capable for the touch sensor routine.
You can see that and more in this video

After watching this
No additional hardware, I just soldered wires to the edges of two beer bottle tops and used them as touch pads.

I’m sure it’s nothing new to all you, Blynkers, but an old Arduino (Atmega) has it too 
True… but required more pins and a voltage divider for a single touch sensor.
@Shadeyman here you can find some sketches to play with.
Isn’t 61.7 ºC a bit high when running idle?

Room temp is 22ºC so its about 40ºC above ambient.
60ºC is hot to touch, even though it says 61.7ºC it doesn’t feel hot, so the temp sensor must be deep inside the cores.
Plus its not exactly at idle, its running a simple code and sending the resulting data over WiFi.
At least his is probably closer to reality… mine runs around 45-51°C but the value I get is about 91-97. So after confirming with an external temp probe, I ‘calibrate’ it by subtracting 46 from the sensor reading. Now every time I use the external probe to double check… it is spot on.
So it seems accurate in variance, just not in the value of the reading… albeit consistently inaccurate, so fixable 
Now the little voltage regulator beside it… that can get very hot… too hot to touch even with a little heatsink… mind you I am using it to power an ESP-01 on the same breadboard as well 
Going to switch that duty to a seperate regulator soon.

Ok, I asked because I’m getting the same temp w/o using WiFi…

}You sure are taking that 5$ board to its extreme
