Bitcoin is the far superior investment for 2020. Not exclusively is it seen as a place of refuge resource, but at the same time it's the first digital money and consistently leads blockchain advancement through it's BIP procedure
If you must hold altcoin because they always bring better profits do not go too deep and make sure your altcoins are top altcoins
Like someone already mentioned that we are having superior investment opportunity with bitcoin and nothing has changed for the year 2020 and we do not need any new advice specifically for this year, within this crypto space we can do what we have already doing for a decade.
Only for the people who want to take high-risk, may be new advice needed specifically for this year. For the people who are believing in to the long term holding of bitcoin definitely never need to take high-risk and holding bitcoin will be more beneficial for them always. After bitcoin we can invest into few highly reputed coins and that also will be coming under low risk category still like many other people I am opting only going with bitcoin for an assured good returns.
