I'm taking Ryan's & other posters' advice - NOT diversifying, but picking a good quality coin that I have very good reason to expect to rise again (have to be sure) but is relatively cheap & out of the public eye at the moment but that people are still throwing money into, & buying in at wholesale prices.
Its funny u mention this cos just this 1 thing alone is what turned my entire altcoin journey right the fuck around. I used to hold 20 random coins with small amounts in each expecting one to take off. But I didnt even realize that even if I got 1000 percent profit on .07 btc I wld only make like .7 btc. I was completely wasting my time taking those uselessly small trades and I couldnt even see it. I was literally blinded by those fake gurus that said you must have a basket of coins at all time to prevent risk
I realized that there is no way in hell that you can properly research and monitor 20 coins at the same time which made a lightbulb go off in my head. It was clear to me that holding 20 different coins was the direct cause of my failure in crypto. I felt so fucking robbed because by that point I had been trading cryptos for nearly 8 months and it was a total nightmare for me. I was one of those guys who would actually be holding a coin as it went up several hundred percent. I even used to celebrate my win with everyone else on twitter and on the forums but what I never revealed to everyone was that I only had like 0.04btc in the trade so i made like $15 profit

Terrible times for me
believe me when i say that I used to jump out of bed in the morning, turn on my laptop, trade {or flush money down the toilet}, go to sleep at night. That was my life for 8 months straight
I hooked up with Ryan because I was at the end of my tether. I had just lost like $400 on librex coin after buying into a pump like a complete numpty.......so I was like FUCK IT i'm turning to the dark side!!! I wanted to be the one dumping on people instead of always having the rug pulled out from under me so I decided to join with Ryan's group
I thought we would be straight up P&D'ing on noobs, and I was happy to do that!!! especially after being on the receiving end of pump and dumps for my entire crypto career up until that point, but surprisingly, that wasn't ryans style, which was quite anti-climatic at first until my second week with the group. Ryan showed me that there are some coins worth trading, and some coins that aren't worth a damn thing. He said that trading is like owning a retail store but also owning a bot that reveals
who is making the most money,
how they are making so much money and
when they are making that money. So all you have to do to also make as much or more money is imitate those players
This week I have only made two trades but its like you said, because I am fully sure of the outcome, I put so much more money into my trades than i used to. Now when a coin goes up even 30% the amount of money I make is substantial and worthwile. I have so many live sell orders placed that sometimes I sit and watch my bitcoins gradually increasing as people buy me out of a coin
I have come far but still have a long way to go, because there are still some people out there who make more than 50 btc a week from alts and that is where i am heading. All I know is that, when I was buying and holding 20 coins at a time I was working so fucking hard but forever losing. So I am living proof that it is much better to narrow your focus to 1 or two coins that you know are going to put money in your hands
