- Try lending
There are wallets with really good offers right now, you can set the time till which you want to invest or lend then get the amount after that.
They only have good offers because the risk is high I could not recommend lending especially when you are storing your funds on a external website because that is insecure and double the risk because you have the risk of the website exit scamming and you have the risk of the people you are lending to running away with your money. I think the hardware wallet advice is the better option at least the risk is little then.
- Invest in other cryptocurrencies as well, not just bitcoins
Bitcoin will always be the safest and easiest to earn a profit with altcoins are risky and I guess OP does not care about a little risk but altcoins are very unpredictable and if he was to invest a large amount into them it could make other investors dump. He would be a whale in most altcoins in Bitcoin his investment is a drop in the ocean.
That's why I wrote - try lending on good wallets.
There are wallets like Zebpay that I have been using since years and the lending option is actually not only safe, but is also under the legislation therefore there is no way that one can scam you in that sector, that would be equivalent to lending money since to even use that wallet you have to submit every single one of your document.
Secondly, it's always a good option to spread out some amount in other cryptos as well, since it's not always about competition rather there are some cryptos like ETH which usually have a synergistic relationship with Bitcoins, when the bitcoins rises, we sometimes see rise in other Altcoins as well, therefore you would be able to make double profits, if done Right. Ofc it would need research but at the end of the day that works out for a lot of people.
