I definitely agree with you OP, and I made myself clear to learn from my past mistakes. Back when I just started out trading and claiming faucets. I was too excited to earn from the coins I bought and sadly by the time I bought them I didnt realise it was pumping, and so I obviously bought them at the highest peak and panicked and sold them at loss. Corrected my mistakes by holding them much longer and reading articles about the market, reading tips from veterans in this forum and did not regret my decision.
Buying ETH will be good for you as the prices for ETH have been so low right now. But what pinches me out here is your holding strategy. Actually altcoins dont have big market so they dont come out of the dip once gone down. So holding would be of not much profit as you would be getting higher margins of profit if you hold bitcoins. So review your decision and see if this can happen.
