This does not convince me. I have got a lot of experience trading altcoins and I can name you dozens of coins under 100 sats which have minimum movements since weeks and months. Even if you spread your investments on 5-10 coins, it will not prevent you from much loss.
I guess you had got luck by choosing some good coins. But you can not derive a profitable trading strategy from it.
So, your trading theory is that every altcoin lower than 100 sats rises automatically within days?

Usually it does, but only if there is some interest in that coin, i mean dont buy up all junk coins.
I edited the OP and put there to buy only coins with daily volume >0.1 btc
