Here i am going to discussed worst cases. Because lot of people adopting to Crypto space and some getting more and some ended up with nothing.
back 2017 i have no experience and new so some execution not got timely.
My worst experience was Not exit at the correct time. there was a ICO it gave me 10X. (6500USD) but i did not exit at the correct time so it went for 400usd.
I sent ETH to unknown escrow. 200$ lost. scammers
Not aware of USDT. Its a very bad experience.
Not concern about Technical analysis.
so today i have massive experience so i know how to play the game. Lets share experiences so enrich newbies knowledge.
Cheers
Well in my case the worst crypto experience that I did is when I hodl Hex token token in just a short period of time and it give me so much regret that I am now seeing how Hex token going almost 1000x its initial price.
