This one i guess is quite simple to the most of you. Recently i am kinda feeling that the smart thing to do would be stop growing my portofolio and start to look bitcoin as the only crypto investment for me.
well, when the bitcoin price rises the altcoins also rise in the ALTCOIN/USD pair and fall into the BTC/ALTCOIN pair, but in time the BTC/ALTCOIN pair recovers and rises and you get many bitcoin and converted to usd you stay with huge profits. of course it can happen that you bought an altcoin and that altcoin drops to 70% of its value causing you to lose money and time.
by that I mean the following, is the best option to you if you buy and hold bitcoin for long time. because this will save you the stress of checking prices all the time... you know that bitcoin is limited and has had a lot of adoption, so the price will raise in the future.
