If you have a demat account, then purchasing Gold ETF is not that hard. Around 80% of my gold is in the form of ETF and only the remainder is in physical form. But you have made the right choice as of now. Gold is not looking very attractive right now. The demand is falling and the price may go further down. But still in the long term (3 to 5 years at least), I can see a lot of potential with gold. It is a "safe" asset with low volatility, and so I have around 10% of my portfolio made up of gold and other bullion metals.
In Bitcoin, only volatility is confusing, but in recent years, everyone who invests in Bitcoin has gotten used to it. I think that for investing for a period of up to 5 years, both gold and bitcoin will be good. Personally, I am more inclined towards cryptocurrencies, but I also consider gold to be a good investment.
