I have some ATOM and MATIC which i see as safer alts, and a small bag of ROSE as a moonshot, but otherwise it’s mostly ETH and BTC.
I started the opposite way but quickly changed course because I felt happier with smaller returns on safer coins.
I think you prefer to minimize the risk which is a good thing too,
Bitcoin and Ethereum are proven to be two coins that need not be doubted and for long term investment it is the right choice because it is safer,
even so it does not mean that when we take a bigger risk it is a mistake because everyone has their own considerations.
It is good to take risk while investing but investing in the wrong coin can lead to big problems. I think it is very safe to invest in these two coins bitcoin and ethereum. it has low chance of losing big money. if you invest in these two coin and wait for a bit long. there will be a chance of good amount of profit. but if you think about another altcoins then you should keep focus in multiple coins like TRX, MATIC, WAVES, SOL etc. these coins has also potential to do well in the future market. but remember that you shouldn’t invest your whole money only for a single coin.
