I understand your point relating to the risk factor of this altcoins but at a point I had to settle down and make close observation into this altcoins and I feel at some point they are worth investing into but extreme caution needs to be taken.
Just the way strategies are applied in accumulating Bitcoin that is how strategic you need to be when buying this altcoins, quote me
here.
Like stated above by @ Ruttoshi, altcoins are not worth investing, and do not think that you can outsmart the altcoin devs because they are the ones in control of the price. A newbie and someone who just started his bitcoin journey shouldn't fuck around with shitcoins because they are for gamblers and not for investors. Investment is something that should exist over a long period of time and not a short term, only greedy people that are after quick profit choose altcoins instead of bitcoin, and at the end they live in regrets.
It is useless to use bitcoin accumulating strategy on shitcoins because it is not bitcoin and doesn't have the potential that bitcoins has. Why will I fool myself to DCA on altcoin, that the value can turn to zero by tomorrow morning. You can buy bitcoin and continue learning and growing your investment but not altcoin because it is the opposite.
Invest wisely, however, I can't tell you what to invest your money on but newbies should stay away from altcoins and stick only to bitcoin investment because no matter how small your portfolio size is, the value of your portfolio will increase with timeline.
