7 btc lost is a pretty steep lesson to learn geeze
I feel sorry for the OP
yeah i've lost at least 40, due to have missed a big opportunity of profit in trading with two old altcoin
but trading is a gabmle, so there is a certain risk involved,
there is no lesson to learn, it will happen again and again
The lesson to take home is to stay away from trading (unless you know a thing or two, lol). Believe me, those who earn by trading on a steady basis are those who can somehow arbitrage the system (know the thing). Even those who are exceptionally lucky to profit by simple trading (epitomized by the "buy low, sell high" mantra) are still doomed if they don't get out in time. Otherwise, as you said, it is not much different from gambling...
And I don't mean just Bitcoin
the good thing is that i have not lost directly those money, the first altcoin was a giveaway, but i didn't sold at the right time, so instead of receiving 20 btc i received only 1, i was hoping to do more, i was to greedy i admit
the second same thing, i instamined it early but i waited too long before selling, and it became worthless quickly
Losing 40 BTC is not the same as not earning 40 BTC, lol. It doesn't feel good either, but not as desperate as actually squandering the money away...
