I advise you put reasonable capital on bitcoin and few funds in altcoin.
I advice you do not give investment advise to others. You can instead give them you technical or fundamental analysis and encourage them to their own research and decide whether or not to out money into an asset or not.
Thank you so much for this very advice and you should also know that even when giving strategies, also state that it's not a financial advice as well.
But I really don't know when the next having might come but one thing I know is that, for all of us who actually missed out of Bitcoin when it was below $20k, now would be one of the best times to buy and hold for the future.
I've lost money personally in Bitcoin, but I see them as lessons I've learnt in a hard way and trying not to let greed and selfishness deprive me from the little gains even while trying to hold for the future.
