In particular, I love that u mention the whole "stop playing for small stakes" thing 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
Yes the higher the stakes the higher the profit
It makes more sense to put more money in to a coin if you want the higher profits
