You are being too generous. Some of those coins will lose value, others will perhaps hold their initial investment value.
We're in a bear market, people. Coins behave differently in a bear market than they do in a bull one.
I won't disagree with this, it's also why I said a lot comes down to BTC price.
The advice I typically give to people who aren't proactive in research and plan to just hold for 12 months is to buy and hold only BTC.
Alts are only good if you have an in and out plan to increase BTC value, holding alts for 12 months with no plan can leave you with less than just holding BTC in a lot of cases, people focus too much on the dollar price of a coin rather than it's sat value, my predictions are in dollar value not sat value, I've predicted 4x for BTC this year, so if you look at 4 of my predictions on that list I'm actually predicting sat value loss, but dollar gain due to BTC climbing.
I had many cases last year where an alts dollar value went up but it lost sat value, if I just kept my money in BTC with a lot of them I would of come out better, in saying that I also had other alts increase my BTC value.
