Good vid, here is my list for 2018 Growth budget, 75% of overall portfolio based on currently available Altcoins would be;
1 Bread - 20% - mobile multicoin wallet/payments etc
2 Ethereum - 20% - stable utility
3 Cardano - 10% - team
4 Neo - 10% - the China bitcoin
5 Bitcoin - 10% - the original
6 ETHLend - 10% - Lending will be big Market especially inAsia/ India and emerging markets with Audience of Billions - SALT is at risk from USA regulators
7 - Verge - 10% Privacy coin with value growth potential
8 - Omisego - 10% - Altcoins payment solutions
The mix is for HODL, growth, no pump and dumps not for day trading / Utility (solving a real problem with hard to copy tech)/ team (passion / track records/ backing/ advisory) / a working (or almost working ) product (cardano exception) with mass adoption - road to market ease, partnerships with Large existing corporations and potential for value growth.
Other 25% of portfolio open for day trading, variations based on Market news and new entries/ rising start into altcoin markets and ICO investing
Having worked in the Banking and Finance space for 15 years, XRP cannot be ruled out, it has powerful and influential backers and is being used by existing globally adopted Investment banks, Institutions and financial systems, the replacement of SWIFT is a seriously big deal in international transactions and ultimately will transform economies and the existing way business is done internationally, if all else fails, XRP may be the last cryptocurrency standing.
This is not financial advice just an opinion.
Have a prosperous 2018!
