That would be a large number of bitcoin if it is a house then maybe he just let it grow then make a profit to buy again a brand new house that is better than the old one. That is a lot of profit if it is a large number of coins.

Yes, it is good to have a minimum saving and then start investing and this way you are a more risk taker investor.

It's saver to save your money in the bank, this way you will be sure that you will make money out of it.
If you invest it you are not hundred pro-cent sure that you will make your money back.   

You can find a countable number of investment sites. But what they provide is very low. Better is to find the trusted site and make your investment. Else just go for gambling you may earn high than investment if you are lucky.

bitcoin investments riskier than gold, due to the fluctuating price of bitcoin and also halving uncertain will make prices go up. but most people say it's going up high. so let's wait

Sure all altcoins is just a gambling of pump and dump,and its where the most people are making good returns ,since they use it and abuse,all days.Sure bitcoin has its volatility but altcoins are the kings now at interest of make your portfolio to grow.In the end investment will be the best way as can bring better results.

Depends on what you want from it, if you want no interest or profit just save it in a saving account, if you want profit however it still depend on the risk you are ready to take on invested money, Low risk with banks and gold IMO and high risk with bitcoin.

i think you have to split the owned capital into 40 percent to 60 percent
40 % for saving
60 for investing (Best way is to trade and own BTC)
thanks

That's a good calculation, but at present saving is a good option as halving is very near. This time halving would give good profit.

i have never liked saving my money when there is a chance of investing it even if it is small investment i always prefer doing it as long as the profit is better than what i get out of the bank annual profit.
