It is never too late to buy bitcoins as there is still probability  for the bitcoins to increase its price, there is no other way or altcoins where people gain huge returns on their investment.

There are different types of wallets hardware wallets and software wallets to store bitcoins and receive bitcoins but one should always keep in mind not to hold or store bitcoins in any exchanges as online exchanges can also act as wallets, exchanges can be used only to buy crypto coins or to transfer to fiat currencies or local currencies.

It is better to invest in bitcoin at the least now, than making it late and regret later when the price shoots greater than the current value as there is potential for the bitcoins to rise in price so better to invest now.

I think from what I have learnt from bitcoin technology is that bitcoin has the capacity to end world poverty and can improve the economic conditions of the world where everyone can enjoy equally financial freedom and live in peace and love, then it will be like heaven on the planet earth for everyone to live in. As this technology gives a source of income and helps people get away from financial burden and live happily, bitcoin can be called the one stop solution for all financial issues.
