I do this way then no risk and i earn good

What i do is i choose altcoins like eth,sol,ltc,trx…and other main altcoins.
I choose the coin wich is lowest from other coins or i think the price quite low.

Then i start simply just buying that coin dca everyday until i have left 40%-50% USDT or USDC so when i have only 50%-60% left USD then i start to find exit point and sell it.
Even If i sell with little profit i have more USD so i can buy more coins and getting bigger money.

My method to trade is to check USD and coin ratio so to make sure i don’t run out of cash.

Little example: initial Investment 100$ i see that ETH price low so i’ll buy everyday without much thinking about it with 2$-3$ DCA – in 10 days i have reached about 30$ in coin so the Critical point and i start to be coutious when to sell the little profit i could make it i’ll sell it.
So i sell for 5% profit wich is small but secure so it’s 1.5$ about so total amount i have for next coin to do same trading 100$+1.5$= 101.5$ so the 1.5$
It’s just example off course do this with bigger money.
Off course one coin at the time once coin done i’ll choose another wich price look like it’s low to me.
