the first question is "how familiar are you with this market?" based on your comment specially the point #5 and the fact that you say you want to buy and hold a bunch of coins, i assume you have no idea how this market works.
so my suggestion is that you should first hang around in the market for a couple of months. and most important of all you should try to see the history of different coins. check their charts in the long run like for a couple of years and see how they have been changing.
try to figure out why each coin rises and falls (aka pumps and dumps) and try to take advantage of that if you want profit.
Im in crypto since september 2017 and reading articles, forums, even global economics everyday, as well learning on technical analysis on a daily basis.
Maybe we didnt understand quite well. I meant that BTC is not technologicaly advanced compared to some other coins and not generaly. And i never said i want to buy bounch of coins...im thinking of geting BTC and 2 or maybe 3 ALTS in top 30 and 2 smallcap coins. And when i say hold for 2 years i didn mean to hold it nomatter what, im gonna definatly sell if i see an upcoming correction.
Based to my resarch im definatly going in
BTC
NEO
Cant decide on
ETH, ADA, LUMENS, IOTA
NULS, NANO, DEEPONION, ICON, XSPEC, VECHAIN, ZILIQA, LISK, 0X, KMD, SONM, POA, BNB and probabaly alot more good coins
There are lots of good coins, but im afraid there is not room for all
Im investing in max 6 to 7 coins
