Maybe stick to altcoins in the top dozen at
CoinMarketCap that have not already been pumped.
Imho, rule #1 is to balance your portfolio:
40% of top10 / top12 coins (BTC, ETH, ETC, XRP, STRAT ...). evenly balanced.
40% of top10-50 "big names" you can find here and there (XVG, WAVES, STEEM, ARDOR, NXT...)
15% of <80M market cap (VOX, BAT, ARK, BAY, VIA...)
5% of ICO (WGR, MCO, ...)
More important:
Read about the coins before you invest.You don't need to understand the technology at 100%, but at least get a good idea of the
use case and the
business model: does this coin address a big market? how its technology makes sense in solving a particular problem? etc...
Don't forget to have a look at the team behing (LinkedIn them).
Here are some of my thoughts, randomly:- I like ARK, they try to make "the blockchain for everybody" and their smartbridge tech looks promising.
- I am ultra-super-duper-bullish for ADROR, because its child chains and business model can make it the next ETH (and ETH seems challenged...). The best coin so far in June 2017 (imvvvvvvho)
- I absolutely love VOX, because they address the AR/VR (virtual reality) market, and it's furiously booming and I believe that users will soon create their own content, using Unity or other 3D tools and will want to sell them (I was in Asia last week at the CES... crazy)
It is a small market, but VOX is still very very under-valuated and could go for a x10.
- I love WGR, because I believe that the blockchain and the smart contracts are perfect for online betting. It makes a lot of sense. I am a bit concerned about their team quality, but so far they are doing a great job and the ICO was perfectly organized. Kudos.
- I have mixed feelings about BAT: they address a huge market (advertisement) and their use case makes sense, but the Ad Market is trusted by tech giants who can bypass them at anytime. I still own some BAT speculatively.
- I also have (had) mixed feelings about STEEM, but this social media creates some buzz and could be a strong competitor to reddit. Moreover, I blogged and made $100 in STEEM on it (happy :-)), so it is "real".
- I love BAY, because they keep it simple and stay within what makes the blockchain awesome: trade and contracts. They value proposition is clear and the technology is good.
- MCO looks cool, it solves a problem, but they will have to fight regulations, and on top of that their business model is not fantastic (low 1% commission, banks will never accept that and could try to "kill" MCO with regulations and lobbying)
I hope it helps. Worst case scenario, you lose everything (be ready for that), but you would have learnt something.
and FINALLY...
the best advice anybody can give you: DON'T TRUST ANYONE ON THE FORUMS... (...especially posts like mine ;-) )
