there's reason why so many big investment firm and companies are having their big share of investments in btc and not in alts because they know it's relatively safe investment and could still gives good ROI.
the thing is, with alts even though sometimes the ROI is indeed multiple folds of btc, but it also carries risk, you could judge if you happened to hold coins like luna and ftt i'm sure by now you're already broke but if you hold btc its just losing some fraction of its value.
while it is safer for Bitcoin to be the choice yet? altcoin shows bigger opportunity for short term investing But the problem is which to choose and how long will it take?
there are several occassion that I do the same strategy buying bitcoin but also buying altcoins for other option.
and this is what have been called diversification .
Indeed, when talking about short-term investments, of course altcoins are still a reasonable choice,
make sure we need to do research before determining which altcoin we invest in,
occasionally it is important to carry out a diversification strategy.completely wrong , Diversification does not have to be occasionally but each time mate , we must have many coin that single investment and this has been proven for how many years now? though determining the coins to keep hold is the harder part but diversifying is what investors in our time now must have and trust me you will also love having those in daily basis.
