my 2 cents to this thread:
Bitcoin - because it is king. There is hell of a lot devlopment going into it, new layers like lightening being devloped and it is the safest bet in the cryptosphere
and as a more risky bet an ultra high potential low cap coin: Stakenet XSN. potential x100 coin. A couple of weeks ago it reached the bottom chartwise and is now gaining momentum again. for the next bull run XSN has a nice set of basics bringing with it:
- staking platform
www.stakenet.io atm for XSN, STRAT, PIVX, DCR and QTUM following these weeks and more after that
---> just deposit your coins there and they will start staking. nothing more to do
- Masternode as a service
- ledger and xeeda support confirmed
- trustless cold staking via TPOS. Means you can have your coins on your ledger, offline and secured, and they will stake anyway via TPOS. XSN is one of two coins who can handle TPOS at all
- the first truely decentralized DEX, being hosted on a network of 1700+ masternodes
- lightening standard based atomic swaps. every lightening coin will be able to be incorporated in their ecosystem
----> Lightening swaps are running already and there is a testnet contest to that in their discord
- crazy cross chain capabilities. via CCPOS you will be able to stake XSN and receive staking rewards in any currency you want. That will even enable "staking" bitcoin
so one will be able to safely cold stake XSN from a ledger and via CCPOS earn bitcoin as a reward. with the underlying growth potential of XSN one has a potential x100 coin and even gains more bitcoin while holding XSN
