i have been hodling in alts for 5 months. I had 1.5 btc when i started. its value is 0.8 now. So...Its your desicion to hodl or not but i advice you to trade if you are good at it or stay in BTC.
Well all coins have their different, i have a coin before and the price was too small that time and because of that i did not sell it ,im just waiting until the price of my token Increase and this will happen. Just research about the coin you want to hold to avoid losing money.
