So, my adventures continue. Ukrainians use the phrase "both laughter and sin" when things are bad enough to bring tears. All we can do is laugh :)...
Dock coins have become my so-called mentor. My first transaction, where I lost some BNB, taught me nothing. I thought it happened because I was an amateur.
CoinMarketCap has been very helpful to me. It's where I research "crypto data". I found out that Dock is indeed traded on certain exchanges. However, there's a catch. My Dock Coins are on the BNB Smart Chain, but to realize my wealth-building plan, I need Dock Coins Dock. Another obstacle: incompatibility.
That’s how I learned about "bridges" — a technology that allows the transfer of assets between different blockchains.
Unfortunately, my Dock Coins turned out to be incompatible with the platforms I chose.
...In the morning, a "parasitic" group with news about Dock (which I didn't delete after my first negative experience) gave me hope. A video guide for swapping my token, which is supported by the same blockchain I have, arrived.
The result: a loss of BNB. :) They are tricky, but bravo!I lost again.
However, thanks to this loss, I learned how to "transfer" tokens between my accounts on exchanges.
For me, this is truly a great experience, as at the beginning of my crypto journey, I didn't even understand the words and meanings.
So, conclusions have been made. I hope that learning won't be so painful in terms of my crypto wallets.

At the same time, I've always lived by the principle of "exchange": if you want to have something, you have to give something...

...Now I want this principle to yield such a return that coins rain down on me from the sky. :)
Thank you to those who read this. Be careful!
